gralloc: Add support for lock_ycbcr

Fill the android_ycbcr struct for HAL_PIXEL_FORMAT_YCbCr_*_888
formats.
This is a flexible YUV format that allows gralloc to set a
hardware specific YUV format based on the usage flags passed in.
Here we set the format similar to how we set the implementation
defined format and set the android_ycbcr structure to point to
the appropriate plane offsets.
Reference:  HAL_PIXEL_FORMAT_YCbCr_420_888 definition in
system/core/include/system/graphics.h
