[PATCH v2 00/10] drm/panel: Remove unnecessary enabled/prepared state

A number of panel drivers track enabled/prepared state (I suspect to protect
regulator refcounts). However, the atomic framework already ensures that
prepare/unprepare and enable/disable calls are balanced. This series removes all
independent tracking from the drivers and adds a WARNING to the core in case
someone uses a panel with a legacy driver.

Changes in v2:
	- Addressed review comments in first patch
	- Since the initial set didn't get much action, this is a partial RESEND
