misc: pmem: Support for dynamic allocation through CMA

A new member, named use_cma, has been added to the struct android_pmem_platform_data.
If use_cma is set to 1, the memory amount of PMEM heap will be dynamically
reserved and then released when it's no more needed through CMA api.
This solution is ready to be used with bitmap allocator.
msm7x30: Simplify the code for hybrid memory allocations on board side

Since we'll never use again PMEM for SF and audio, let's simplify
the code for hybrid memory allocations (ION + PMEM for ADSP).
msm7x30: Allow to optionally enable the use of CMA for ION MM and PMEM ADSP heaps

Add two new config options to enable or disable the use of CMA in order
to dynamically or statically allocate the memory needed by ION MM and
PMEM ADSP heaps.
msm7x30: Use CMA for PMEM ADSP

Dynamically allocate, through CMA, the memory needed by camera
and camcorder by setting use_cma = 1 for PMEM ADSP.
msm7x30: Update defconfigs

Enable the option to use CMA for ION MM heap and for PMEM ADSP heap.
msm7x30: Use a higher memory allocation if CMA is used for ION MM heap

When CMA is used for ION MM heap, it could be required that a higher amount of
memory is temporarly allocated while starting the playback of some HD videos
or while re-encoding a long video before sending/sharing it with an app
(for example WhatsApp).
