drm: bridge: adv7511: enable CEC support for ADV7535
Like the ADV7533, the ADV7535 has an offset for the CEC register map,
and it is the same value (ADV7533_REG_CEC_OFFSET = 0x70).
Rather than testing for numerous chip types in the offset calculations
throughout the driver, just compute it during driver probe and put it in
the private adv7511 data structure.
