Subject: [PATCH] fix-glamo-mci-ensure-more-than-74-clocks-after-power.patch

We are meant to run SD_CLK a little while after power-on for the SD
Card, but with the no idle clock changes we didn't take care about it.

This makes us sleep a little bit before disabling clock if we just
powered up the SD Card.
