mmc: sdhci: Do not use spin lock in set_ios paths The spin lock is not necessary in set_ios. Anything that is racing with changes to the I/O state is already broken. The mmc core already provides synchronization via "claiming" the host. So remove spin_lock and friends from sdhci_set_ios and related callbacks.
