media: coda: fix frame_mem_ctrl for YUV420 and YVU420 formats 

[ Upstream commit 44693d74f5653f82cd7ca0fe730eed0f6b83306a ]

The frame memory control register value is currently determined
before userspace selects the final capture format and never corrected.
Update ctx->frame_mem_ctrl in __coda_start_decoding() to fix decoding
into YUV420 or YVU420 capture buffers.
