5bc176b1a6 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.

0f6dc7ea55 Add support for allocating YUV formats 
Currently they're all allocated in pmem, instead of pmem_adsp.

e17d093d0c improve cache behavior of gralloc allocations on qsd8k 
make sure to use cached buffers only when frequent cpu access is needed.
also, always flush buffers after they are allocated and cleared.

be6f97aad3 libgralloc-qsd8k: Do not use the physical address of surfaces/framebuffer 
The GPU now correctly maps everything throug hthe MMU so physical addresses
are no longer needed.

b73f40535f 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.

717cf60b7a 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.
