pinctrl: mvebu: dove: provide generic mpp callbacks
We want to get rid of passing register addresses to common pinctrl driver, so provide set/get callbacks that use generic mpp pins helper and will be used later. While at it, also make use of globally defined MPP macros. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>
