media: sun6i-csi: Configure registers from format tables

Switch over to using the static format table descriptions to configure
registers. Rework the hardware configuration helpers to leverage
information from the format structures and benefit from their logic.
Remove the previous dedicated helpers.

The intention is to make the interaction between the different formats
and the hardware side more visible and clear.
