[PATCH] USB: Remove __attribute__ ((packed)) for struct ehci_hccr and ehci_hcor.

Remove __attribute__ ((packed)) to prevent byte access to soc
registers in some gcc versions.

Having patches to enable ehci for the BeagleBoard lying around for
several month, this one was the show-stopper.

Credits have to go to Laine Walker-Avina <lwalkera <at> ieee.org> for
finding the problem.

[PATCH 3/3] 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.
