Errors in isp are handled in soft irq context, putting a wait for
cdm done is not allowed. Add atomic flag for checking status of
cdm and check it before reg dump to determine the request for
which register values can be dumped in command buffer.This is
only applicable to reg dump on error.

If the resource for which BUF_DONE event has come is already
signalled in the oldest request, this BUF_DONE could be for
the next request in the list. This can happen if the IRQ
handling for BUF_DONE is delayed and by the time it is handled
if the resources for the next request are already signalled
along with other pending resources for the oldest request,
we might handle resources which corresponds to next request
first. If we do not look into next request and thus if we
ignore these BUF_DONEs, we will never be done with the next
request.

Use pr_info for camera warning and error logs to avoid sending
to console (assuming info logs are disabled to console).
All camera warning and error logs are anyway tagged with
CAM_WARN and CAM_ERR, so using pr_info doesn't cause any
information loss.

Shutter notification must be sent when moving request
to free list if it was not sent out earlier due to

Currently EPOCH IRQ handling is at a higher priority
compared to RUP IRQ as RUP is fired at bus level. If
RUP IRQ is not scheduled for handling by the time we
receive EPOCH IRQ, EPOCH IRQ will be processed first
and this will lead to missed SOF notification as the
active request list might be empty. This change sets
priority of both IRQs to the same by utilizing a new
IRQ controller that is tasked with handling RUP from
BUS. BUF_DONE is also subscribed to the same VFE top
level BUS_WR IRQ but with a lower priority. IRQs for
CAMIF Lite and RDI are subscribed to only if the ctx
is RDI only.
