ARM: 7219/1: mmc: mmci: Change vdd_handler to a generic ios_handler
The purpose of the vdd_handler does not make sense. We remove it
and use a generic approach instead. A new ios_handler is added, the
purpose of which e.g. can be to control GPIO pins to a levelshifter.
Previously the vdd_handler was also used for making additional
changes to the power register bits. This option is superfluous and is
therefore removed.
Adaptaptions from the old vdd_handler to the new ios_handler is done for
mach-ux500 board, which was the only one using the vdd_handler.
This patch is based upon a patch from Sebastian Rasmussen.
