SYSLINK: ipc - listmp updated for SysLink 2.0

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
IPC modules.
1. A listmp_module variable is introduced to mimic the BIOS behavior.
