Subject: [PATCH 0/4] Venus stateful encoder compliance

Hello,

Тhis patchset is an attempt to make Venus encoder driver compliant with
stateful encoder spec. There are still few details which need to be
cleaned up so this can be treated as WIP. For example the usage of m2m
helpers to update the states and handing of the LAST capture buffer for
Drain state. Here mainly I re-designed the driver to able to handle
capture/output queues independently and properly go in and out of Reset
state.

These patches depend on [1].  

Comments are welcome!

regards,
Stan
