MLK-17703-7: drm: imx: dcss: configure output pipe according to what sink supports

Output pipe tables' configuration was hardcoded. This patch will allow the output
pipe to be configured according to what the sink supports.

Also, since there's no way to pass gamut and nonlinearity settings from userspace,
configure the input pipe as REC2020/REC2084.
