msm: camera: cci: Add rd_done to handle read done operation

Currently reset_complete and rd_done operation is flagged with same
irq handler reset_complete. Sometime complete on reset_complete also
been catched by wait for read done operation, which allows to perform
wrong operations for read done. This sceneraio generates wrong operation
which includes, rd_underflow/rd_done. This change adds rd_done
attributes to differentiate the operation. Also, there is a race
condition for cci device ref count, when multiple submodules try to
do cci_init parallely, reference count will be out of sync. This change
adds mutex for reference count as well as to be the ref_count in sync.
This change also adds some irq error mask to identify errors for
debuggind purpose.
