video: driver: add support for cyclic intra refresh

Currently driver supports only random intra refresh, extend
it to support cyclic intra refresh too.
Cyclic intra refresh is supported dynamically as well.
- If intra refresh type is set and num of LCU’s to be refreshed
  are non-zero before session start, intra refresh will be enabled
  throughout the session.
  Any further dynamic settings in the number of LCU’s including 0
  will be honored accordingly.
- If intra refresh type is set and num of LCU’s to be refreshed are zero
  before session start, intra refresh will be disabled.
  When client sets it to non-zero value dynamically, driver will set
  HFI_PROP_REQUEST_SYNC_FRAME with
  HFI_SYNC_FRAME_REQUEST_WITH_PREFIX_SEQ_HDR.
  Driver needs to send HFI_PROP_REQUEST_SYNC_FRAME only at time of
  CIR Enable, no need to send at time of disable/enable again.
