sdhci: Enable only relevant (DMA/PIO) interrupts during transfers

Some hosts (that is, FSL eSDHC) throw PIO interrupts during DMA
transfers, this causes tons of unneeded interrupts, and thus highly
degraded speed.

This patch modifies the driver so that now we only enable relevant
(DMA or PIO) interrupts during transfers.
