media: coda: Add a V4L2 user for control error macroblocks count
To avoid potentially overflowing the kernel logs in the case
of corrupted streams, this commit replaces an error message with
a per-stream counter to be read through a driver-specific
control.
Applications can read the per-stream accumulated
error macroblocks count.
The old error message is replaced by a rate-limited debug message.
