drm/panel: samsung: Add shared test key helpers

Browse source

Several Samsung display controllers use identical commands to enable
and disable their three levels of test keys. The drivers currently
duplicate these commands in local macros.

Move the commands to typed helpers in a private Samsung DSI header and
use them from the drivers which already identify the commands by their
test key level.
