Subject: [PATCH 0/3] drm/bridge: ps8640: Make sure all needed is powered to get the EDID

The first patch is not really related and can be picked alone. The
second and the third are to rework the power handling to get the EDID.
Basically, we need to make sure all the needed is powered to be able
to get the EDID. Before, we saw that getting the EDID failed as
explained in the third patch.

Note that this series depends on:

to apply cleanly.
