[PATCH v7 16/28] media: mediatek: vcodec: support single allocation buffer

The buffer count of capture format V4L2_PIX_FMT_MS21 is different with
V4L2_PIX_FMT_MM21. V4L2_PIX_FMT_MS21 has two memory to store luma and
chrome planes, V4L2_PIX_FMT_MS21 only has one. Adding condition to
separate them.
The dma address is secure handle for secure video playback, the handle
may not aligned with 64.
