Some device drivers (panel backlights especially) need to follow precise

These sequences are board-specific, and do not belong to a particular
driver - therefore they have been performed by board-specific hook
functions to far.
The sequences are not board-specific, they are device (backlight, etc.)
specific. The sequences have been handled in board-specific hook
functions so far because there hasn't been proper drivers for the
devices.

If I were to take the same panel (and backlight) you have and install it
on my board, I would need the same power sequence.
