Since we don't run in the atomic context any longer, we can turn mdelay()s into msleep()s. The only place where the driver is still using mdelay() is sdhci_send_command(). There it is possible to use sleepable delays too, but we don't actually want to force rescheduling in a hot path. Sure, we might end up calling msleep() there too, just not via this safe patch.
