[U-Boot] [PATCH] arm: omap3: Fix beagleboard SPL boot hangup (GPIO clocks not enabled)

Patch f33b9bd3 [arm: omap3: Enable clocks for peripherals only if they are used] breaks SPL booting on Beagleboard. Since some gpio input's are read to detect the board revision. But with this patch above, the clocks to the GPIO subsystems are not enabled per default any more. The GPIO banks need to be configured specifically now.

Ok, this is one of the problem that we can have with the new patch.
Thank you
