regulator: rpi-panel: Convert to drive lines directly

commit 4866e35e

 upstream.

The Atmel was doing a load of automatic sequencing of
control lines, however it was combining the touch controller's
reset with the bridge/panel control.

Change to control the control signals directly rather than
through the automatic POWERON control.
