osal: add RGB lock support

When RGB buffer is allocated by gralloc, this patch allows to lock
for this buffer with ion_map() since that for the RGB format buffer,
gralloc uses PVR own function to virtual address mapping instead of
ion_map().

The flag GRALLOC_USAGE_HW_VIDEO_ENCODER is used to aware the buffer
is RGB format in gralloc.
