mmc: sh_mmcif: add regulator support

Browse source

Add regulator support to the sh_mmcif driver, but also preserve the current
power-callback.

Also note, that the card power is not switched off during clock gating
periods, hence there's no need to power it on every time the card is
re-activated.
