This commit broke USB on olinuxino board:

  87b9bea USB: host: hub: Use usb_hub_power_on from U-Boot

This patch was ported from U-Boot with small changes. See discussion:
http://lists.denx.de/pipermail/u-boot/2013-May/153920.html

The root cause seems to be a missing mask and missing 'break' in
ehci-hcd.c. Fix both.
