arch/arm/sama5: Make EHCI work with slow devices.

Make low/full speed devices work with EHCI while OHCI is disabled. A
high speed USB hub has to be plugged into the root hub. This change
will also allow the optional use of a full speed hub between the
high speed hub and the low/full speed device. A recursive mutex is
used to avoid deadlocks.
