Subject: [maemo-leste] [PATCH] Revert "mmc: disable UHS modes if Vcc cannot be switched on and off"
This reverts commit 04a2ea248f58b3b6216d0cd0a6b8698df8b14355.

That commit is causing reboot loops on Nokia N900 and basically make U-Boot
on Nokia N900 unusable. Revert it for now until problem is solved.

After reverting that commit U-Boot on Nokia N900 is working again.
