This patch supports different clock sources for omap4 dmtimers.
Specifically, dmtimers[5,6,7,8] have syc_clk_div_ck as parent clock,
while dmtimers[1,2,3,4,9,10,11,12] have sys_clkin_ck as the parent
clock.
Tested on OMAp4430 SDP.

Since the current clock framework code doesn't wait on idlest, the registers
can gets accessed before the clock is being enabled and stable
This leads to crashesh. One of the crash seen is with 1 GHz MPU speed

The function iommu_get_plat_data_size is used outside of the iommu
and needs to be exported when building as modules. Also, the omap_iommu_class
is created in the module init in iommu.c but isn't destroyed in the module
exit which prevents the ability to repeatedly load and unload the module.
These issues are fixed in this patch.

In order to make SysLink into loadable/unloadable modules, the
notify, notify_ducatidriver, and syslink_ipc modules were combined
into one module. This needed to be done because of the circular
dependencies that exist between the three modules. Also, the
platform_mem file had to be moved to its own module.
There are corresponding user-space changes needed with this patch.

This is part of migration to SysLink 2.0. The platform module still serves
very much the same purpose as before. However, some major changes have
been introduced:
- Handles setup/destroy of individual IPC/notify modules. This was previously
done by sysmgr module.
- Reading/writing config info to shared memory is done by this module. This
was previously done by sysmgr module.
- Creation/opening and deleting/clsoing of IPC/notify module instances has been
removed. Previously it was done in the start/stop callback functions. It
has been moved to the new ipc module.
- platform_override_cfg has been moved into platform.c and platformcfg.c has
been eliminated.

Major changes:

functions.

The notify ducati sharedmemory driver module is updated for SysLink-2.0.
This version incorporates the changes for improved ease of programming for
the user.
The following are the main changes specific to this module:
1. The notify ducati shm driver is no longer present on the user-side.
The character driver code has therefore been removed.
2. WARN_ONs have been added in place of BUG_ONs and unlikely macros are added
for compiler branch prediction improvement.
3. cache calls are added, but commented out.

Created a new heapmemmp module for SysLink-2.0. This module is a
shared memory heap that allows allocation of variable-sized blocks, in
contrast to heapbufmp, which allows fixed-size blocks.
In addition to the new feature of variable-length allocation, heapmemmp also
incorporates generic changes common to all modules in SysLink 2.0 like:
- heapmemmp_module pointer to heapmemmp_state object.
- More user-friendly APIs.
- heapmemmp_open opens by name.
- heapmemmp_open_by_addr opens by shared memory address.
- create() function calls post_init() function at the end.

Added new module heapbufmp for SysLink-2.0. This version
incorporates the changes for improved ease of programming
by the user. It replaces the old heapbuf module.
New features:
- Added heapbufmp_module pointer to heapbufmp_state.
- More user-friendly API.
- heapbufmp_open opens an existing heapbufmp by name.
- heapbufmp_open_by_addr opens an existing heapbufmp by shared address.
Fixed bugs in heapbufmp:
- heapbufmp_alloc was using obj->params.exact instead of obj->exact to
check whether exact allocation was required.
- heapbufmp_open_by_addr was using the list iteration macro the wrong way.
- heapbufmp_ioctl_open_by_addr was not converting srptr to normal address
before passing it to heapbufmp_open_by_addr.
- heapbufmp_ioctl_close was passing the handle rather than the handle ptr
to heapbufmp_close.
Also added some WARN_ONs to heapbufmp error checks.

listmp module is updated for SysLink-2.0. This version incorporates
the changes for improved ease of programming for the user.
The following are the main changes specific to this module:
1. The listmp_sharedmemory module and listmp base module have been merged
together. The listmp module is essentially deleted and the listmp_
sharedmemory module became the defacto listmp module. All files have
been renamed accordingly.
2. listmp_get_gate API is added to return the gatemp object used for the
listmp object protection. listmp_open API is split into two API -
listmp_open and listmp_open_by_addr. The open function takes in a name,
and the open_by_addr function takes in a shared address. Both these API
do not take any params structure as done previously.
3. listmp_params_init function does not take any object handle. The return
type has also changed.
4. listmp_shared_mem_req return value changed.
5. listmp_config, listmp_attrs and listmp_params structure elements have changed.
The attrs structure stores the shared address of the gatemp object and also
contains the head of the shared memory linked list. Some other elements have
been removed/replaced.
6. listmp_object definition has changed and restructed. It removes some of the
additional layers. The new structure can store the shared region id, it's
cacheability properties, and the gatemp handle that will be used to protect
it.
7. gatepeterson_ function calls have been replaced with the corresponding
gatemp_ function calls.
8. WARN_ONs have been added in place of BUG_ONs and unlikely macros are added
for compiler branch prediction improvement.
9. cache calls are added, but commented out.
The following are the changes in line to the common changes to all SysLink-2.0

region id, it's cacheability properties, and the gatemp handle that will be
used to protect it.
