mmc: sdhci: check interrupt flags in ISR again
When using MSI it is possible that a new MSI is sent while an earlier
MSI is currently handled. In this case SDHCI_INT_STATUS only contains
SDHCI_INT_RESPONSE and the ISR would not be called again. But at the end
of the ISR SDHCI_INT_DATA_END is now also pending which would be ignored.
Fix this by rereading the interrupt flags in the ISR until no interrupt
we care is pending.
