This leads to card-detect interrupts staying disabled. Do not disable card-detect interrupts on DATA IRQs.

Re-testing this patch has again become possible now, after Magnus has posted his INTC and the "tmio_mmc: use 100ms mmc_detect_change() delay" patches. Successfully tested on Migo-R (sh7722) and MS7724SE (sh7724).
