While working on my other series related to gpio-backlight[1] I noticed
that we could simplify the driver if we made the only user of platform
data use GPIO lookups and device properties. This series tries to do
that.

The first patch sets up all the required structures in the board file,
the second modifies the backlight driver, the third and fourth remove
the leftovers.

This series depends on the three first patches from [1].

I don't have access to this HW but hopefully this works. Only compile
tested.
