drm/bridge: analogix_dp: Improve panel on time

In order to reduce the time required to turn on the panel, this patch
makes 2 assumptions:
1- In detect(): if there's a panel, we're connected.
2- In get_modes(): if there's a panel, let the panel driver decide if
   it should prepare/unprepare in order to get the modes.

The first is straightforward, and shouldn't need further explanation. The
second should eliminate the prepare/unprepare delays from get_modes() in
most cases, since panels generally hardcode their modes in the driver as
opposed to reading EDID. If a panel does need to read EDID, it should be
responsible for ensuring it's in a state in which it can.

increment the software vblank counter before the changes being committed

that any old vblank interrupt gets to the handler and then uses

before the .atomic_disable() func is called.
To get the crtc of the plane, read old_state->crtc instead of
