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
Changes in v3: - Fixed typo in docs - Moved static inlines out of header - Used helper function to make the state transition - All panel driver patches are the same as v1
