mmc: sdhci: don't clear SDHCI_INT_STATUS register during CMD_INHIBIT
Fixes emmc initialization regression on the db410c platform.
Clearing this register while SDHCI_PRESENT_STATE reports
SDHCI_CMD_INHIBIT leads to undefined behaviour on the db410c.
When commit 7dde50 was merged (mmc: sdhci: Wait for SDHCI_INT_DATA_END
when transferring), SDHCI transfers transitioned to wait for bit
SDHCI_INT_DATA_END before flagging transfers done.
Without this patch, the db410 platform fails to initialize its eMMC
due to all of its transfers timing out (SDHCI_INT_DATA_END is never
raised after all the blocks have been transferred).
