media: v4l: Add 32-bit packed YUV formats
The formats added in this patch include: V4L2_PIX_FMT_AYUV32 V4L2_PIX_FMT_XYUV32 V4L2_PIX_FMT_VUYA32 V4L2_PIX_FMT_VUYX32 These formats enable the trasmission of alpha channel data to other drivers and userspace applications in addition to YUV data. For example, buffers generated by drivers in one of these formats can be used by the Weston compositor to display as a texture or flipped directly onto the overlay planes with the help of a DRM driver.
