arch/arm/sama5: Fix OHCI SchedulingOverrun interrupt storm.

Browse Source 
The following message is printed continuously and the nsh
shell is unusable on sama5d3-xplained.
"OHCI ERROR: Unhandled interrupts pending: 000001". This
happens when a keyboard is removed and reinserted on
port3 (lower port) while a bluetooth dongle is in port2.
