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 more generic approach instead. A new "ios" handler is thus
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 MMCIPOWER register bits. This option is now removed.
This patch is based upon a patch from Sebastian Rasmussen.
