media: s5p-mfc: Support for handling RET_ENC_BUFFER_FULL interrupt
When output encoded buffer size provided by userspace
is insufficient with current encoding parameters, it
leads to RET_ENC_BUFFER_FULL interrupt which was not
handled in IRQ handler.
On handling of RET_ENC_BUFFER_FULL interrupt leads to
NAL_ABORT command from host to risc which in turn leads
to RET_NAL_ABORT interrupt. On receiving RET_NAL_ABORT
driver clears workbit and VB2 queues for cleaner closing
of MFC instance.
When user encounters "Call on DQBUF after unrecoverable
error", userspace should close fd and restart with larger
output encoder buffer size.
