mediatek: Change android flexible format to allocate YVU420 buffer

crrev.com/c/1716864 made gralloc allocae NV12 buffer with the android flexible
format, DRM_FORMAT_FLEX_YCbCr_420_888. However, the change broke many CTS tests.
This partially reverts the commit. The allocated buffer fromat becomes YVU420.
