V4L/DVB (9244): video: improve sh_mobile_ceu buffer handling

Browse source

This patch improves the buffer handling in the sh_mobile_ceu driver.

Instead of marking all queued buffers as VIDEOBUF_ACTIVE the code now
marks queued-but-not-active buffers as VIDEOBUF_QUEUED and buffers
involved in dma as VIDEOBUF_ACTIVE. The code is also updated with
code to cancel active buffers, thanks to Morimoto-san.
