only set the PRIV_FLAGS_NEEDS_FLUSH flag on PMEM buffers
PRIV_FLAGS_NEEDS_FLUSH will trigger an ioctl call into the PMEM
driver in unlock(), so it makes not sense to set this flag for
non pmem buffers.

Refactor the qsd8k gralloc implementation.
The purpose of this change is to add support for allocating gralloc buffers
from either /dev/pmem or /dev/pmem_adsp depending on the usage flags. It does
this by factoring out and abstracting the interactions with the pmem device.
For /dev/pmem allocations, the kernel allocator is not used, so a single master
fd is opened, and all the allocations are sub-allocated from that by gralloc.
For /dev/pmem_adsp the kernel allocator is used, so it simply opens a new fd
for each allocation.
A very basic unit test that can be run on the host is included. It requires
gtest, so to run it on a host system gtest must (currently) be compiled with
BUILD_WITH_ASTL=true.

part of fix for [2363506] [Sapphire] Video playback broken
make sure to reject incompatible buffers in special function
GRALLOC_MODULE_PERFORM_CREATE_HANDLE_FROM_BUFFER
we use ioctl(PMEM_GET_SIZE) to validate that the given buffer is indeed
a pmem buffer.

fix[2222341] Soft reset while going back from camcorder settings
add a way to convert a mapped "pushbuffer" buffer to a gralloc handle
which then can be safely used by surfaceflinger
also make sure to not send empty rectangles to the MDP.

fix gralloc qsd8k. we actually don't need to use /pmem/gpu1, since the gpu is now able to use regular PMEM.
this module is now closer to the generic gralloc module, although it will have to evolve in the near future.
