mb/google/rauru: Support the panel with a load switch control

Browse source 
The Rauru follower device goes `load switch` path to ensure the
discharge timing meets the panel power-off sequence. Refactor panel.c to
support this hardware change.

Remove PANEL from fw_config since this is a board-specific change.
