In current venus driver, the unified frequency table is aligned
with the downstream decoder table which causes performance issues
in encoding scenarios. Fix that by aligning frequency table on
worst case (encoding).

According to the ov5640 specification (2.7 power up sequence), host can
access the sensor's registers 20ms after reset. Trying to access them
before leads to undefined behavior and result in sporadic initialization
errors.

OV5640 sensor supports raw image output (bayer).
Configure ISP mux/format registers accordingly.

I've just tested this with a dragonboard-410c (MICPI/CSI) + OV5640 sensor.
It works on my side for 1280*720, 1920*1080 and 2592*1944 formats.

It works for me on Dragonboard 410c + D3 camera mezzanine (ov5640) .
Any comments on this change?

Deblocking filter allows to reduce blocking artifacts and improve
visual quality. This is configurable via the V4L2 API but eventually
not applied to the encoder.
Note that alpha and beta deblocking values are 32-bit signed (-6;+6).
