minigbm: add DRM_FORMAT_YVU420_ANDROID
YV12 in <system/graphics.h> in the Android tree defines the
HAL_PIXEL_FORMAT_YV12 as:
* y_size = stride * height
* c_stride = ALIGN(stride/2, 16)
* c_size = c_stride * height/2
* size = y_size + c_size * 2
* cr_offset = y_size
* cb_offset = y_size + c_size
Let's add a special format DRM_FORMAT_YVU420_ANDROID that adheres to these
requirements.
Previously, our y_size on Intel not adhere to the spec. We should
change drv_bo_from_format to calculate the size of plane not based on the
aligned height, but the height that outside world sees.
