To use the so called powered-on re-initialization of an SDIO card, the
power to the card must obviously have stayed on. If not, the initialization
will simply fail.
In the runtime suspend case, the card is always powered off. Hence, let's
drop the support for powered-on re-initialization during runtime resume, as
it doesn't make sense.
Moreover, during a HW reset, the point is to cut the power to the card and
then do fresh re-initialization. Therefore drop the support for powered-on
re-initialization during HW reset.
