Subject: [PATCH 7/7] media: venus: Set buffer to FW based on FW min count requirement.
- Get the min buffer count required by FW from source event change
and use the same value to decide actual buffer count and for
buffer size calculation.
- Setup DPB and OPB buffers after session continue incase of
reconfig.
