This one does have a seperate card-detect-irq (which is not populated
for sdhi2) while the other one only has one, generic irq. That's at
least a difference.

We could try to see if there are unexpected card-detect events by
instrumenting mmc_detect_change() in tmio_mmc_pio.c, but my feeling is
that the card_busy change you reverted is only making something visible
which went wrong before the change, also.

So, it might be worth to protect the whole voltage_switch and card_busy
functionality with TMIO_MMC_MIN_RCAR2?
