Fixed size calculation for the allocated buffer into which the
packing takes place.
Tested using V4L2 unit tests and debug prints as only V4L2 uses this
function.

Since Kconfig entries have been moved to drivers/media/Kconfig,
we need to enable media support in order for dmm/tiler to build.

The reference count of blocks increases on alloc, and by registered
buffers that contain that block.
When all tiler drivers of a process are closed:
- blocks allocated by it are marked "freed"
- buffers registered by it are unregistered
All blocks that are no longer marked "allocated" and are not
referenced by registered buffers are actually freed.
Blocks allocated by the kernel API are tracked separately, and
are not release when tiler drivers are closed. They are only
freed using tiler_free, or when the kernel driver closes.
Fixed a bug with querying buffers by address, which did not
account for the new TCM support for 1D buffers and block management.
Added support for clearing PAT for freed blocks.
Added extended tiler kernel API-s for specifying group ids, pids,
alignment and offset.

Removed unnecessary true/false identical macro values
Changed tcm_area.type field to is2d
Shortened variable names
Renamed functions based on what they do
Simplified some of the logic
Removed most of the debug messages and unused/duplicate variables
Removed duplicate parameter checks and made fuctions that always
succeed void.
Moved tcm_dbg.h macros into tcm_utils.h
Tested using memmgr_1.0 tests.

Changed the way tiler blocks are maintained. 1D blocks are maintained
similarly as before, but 2D blocks now reside on "reserved areas" that
are maintained in area_info structs.
Note, that even though auto-packing is supported, there is no open API
to specify alignment other than kernel page size. Therefore, there is
no expected allocation efficiency gain.
Reference counts are also introduced although they are not yet used.
Tested using memmgr_1.0 test as well as select allocation/freeing
kernel calls to verify logic of maintaining blocks in the reserved area.

Fixed spacing and most comments according to kernel coding style.
Fixed multi-line strings.
Made all function signatures static.
Replaced memset initialization with "= {0}".

we introduce two new dmm APIs --dmm_get_pages/dmm_free_pages --
to the tiler driver, which allocate and free a set of dmm pages.
previously, we allocated/freed single pages using
dmm_get_page()/dmm_free_page. we observed that moving
single pages from the used page stack to the free page
stack caused excessive delays because of linear/unsorted
searches.

Issue if power_saving option passed from board file and CONFIG_PM not define.
This is because hosts refer to wrong operation table and that try to power save.

In the _setup() hook, check for valid IDLEST fields. If not set, use
the module defaults since they are the same as the module defaults
for most hwmods.
Problem found because _wait_target_ready() will fail if IDLEST
fields are not valid.
