drm/bridge: analogix_dp: Split the platform-specific poweron in two parts
Some of the platform-specific stuff in rockchip_dp_poweron() needs to happen before the generic code. Some needs to happen after. Let's split the callback in two. Specifically we can't start doing PSR work until _after_ the whole controller is up, so don't set the enable until the end. Cc: Kristian H.
