mmc: sdhci: allow sdio interrupts while sdhci runtime suspended
Allow SDIO interrupts to be received while the SDHCI host is runtime
suspended. We do this by leaving the AHB clock enabled while the
host is runtime suspended so we can access the SDHCI registers, and
so read and raise the SDIO card interrupt.
