This series converts various OMAPFB drivers to use the newer gpiod API
that respects line polarity specified in DTS.

Unfortunately existing DTS files specify incorrect (active high) polarity
for reset lines. As discussed in [1] we will not try to correct existing
DTSes, but instead follow the path established by DRM drivers for the same
components, and continue using inverted polarity in the FB drivers.

Sorry, it looks like I did not clear temporary directory, so there is a
bit of mess in the patches. I'll resend properly in a second.
