This is just code motion of the probe routine to move all the things
that are for the "whole chip" (instead of the GPIO parts or the
MIPI-to-eDP parts) together at the start of probe. This is in
preparation for breaking the driver into sub-drivers.

Since we're using devm for all of the "whole chip" stuff this is
actually quite easy now.
