[PATCH v4 0/4] Fix up Nokia 770 regression

A recent change to use dynamic GPIO base allocation in the
OMAP GPIO driver caused a regression in some OMAP1 boards.
This series fixes up the Nokia 770 board from 2005:

I don't know how urgent the fix is, you decide. For me,
it is fair if fringe systems get fixed in due time, as
they are hardly anyones main development laptop.
