Alexander Holler d90859a67c omap3_beagle: enable EHCI and USB storage.
The reset sequence/configuration for ehci is highly board specific,
so this will be done in the source for the board, instead of
introducing several CONFIG_* which would be needed to make those
few lines in beagle.c usable across different OMAP boards.
