Harro Haan c6c352371c ARM: 5965/1: Fix soft lockup in at91 udc driver 
Fix a potential soft lockup in the AT91 UDC driver by ensuring that
the UDC clock is enabled inside the interrupt handler. If the UDC clock is not enabled then the UDC registers cannot be written to
and the interrupt cannot be cleared or masked.

Note that this patch (and other parts of the existing AT91 UDC
driver) is potentially racy for preempt-rt kernels,
but is okay for mainline.
