pinctrl: sh-pfc: refactor voltage setting

Browse source

All known hardware being able to switch voltages has the same POCCTRL
register. So, factor out the common code to the core and keep only
the pin-to-bit mapping SoC specific. Convert the only user, r8a7790.
In case POCCTRL should ever get more complex (more voltages to select?),
we should probably switch over to a describing array like drive strength
does currently.
