- hierarchical state model which comprises of
top level states and sub states
- top level states include OPEN, CLOSE, ERROR,
INPUT_STREAMING, OUTPUT_STREAMING, STREAMING.
- sub states include DRAIN, DRC, DRAIN_LAST_BUFFER,
DRC_LAST_BUFFER, INPUT_PAUSE, OUTPUT_PAUSE.
- follows deterministic approach for key sequences
like DRC, DRAIN and last flag handling i.e none
of these events are ignored or discarded.
- removal of auto start of firmware input port as
part of ipsc handling.
- introduction of hfi commands for host controlled
PAUSE and RESUME of firmware ports.
- introduction of information last flag packets
for DRC and DRAIN when FW has insufficient
output buffers.

Incase of synchronous cmd(HFI_CMD_INIT, HFI_CMD_STOP, HFI_CMD_CLOSE)
timeout cases, video driver will attempt to do core_deinit sequence
and will free all interface queues mappings as part of core_deinit.
If at same time ISR handler is fired then reverse thread will attempt
to dequeue packets from message and debug queue. Reverse thread will
not acquire core->lock for performance reasone. Dequeueing packets
without acquiring core->lock might lead to use-after-free issues.
Uploaded change to address above mentioned issue.

Critical priority - A video session which is prioritized above
all concurrent sessions. Such sessions have low latencies and
at the same time they cannot be rejected due to overload.
Reserve duration - Duration by which a session reserves the
video hardware for processing frames from that session.
Both the above aspects are implemented with these changes.

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.

Upstream recommends to use readl_relaxed_poll_timeout instead of reading
register in a loop with sleep. So replaced with readl_relaxed_poll_timeout
in all possible places.
