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.

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.

We really need to fix this eventually, but it's not a ship blocker.

The GPU now correctly maps everything throug hthe MMU so physical addresses
are no longer needed.
