drm/bridge: adv7511: Rework adv7511_power_on/off() so they can be reused internally
commit 651e4769ba2a9f20c4b8a823ae2727bf7fa9c9f0 upstream.
In chasing down issues with EDID probing, I found some
duplicated but incomplete logic used to power the chip on and
off.
This patch refactors the adv7511_power_on/off functions, so
they can be used for internal needs.
