ARM: at91: rm9200: fix usb device clock id 



Referring to the datasheet the index 2 is the MCKUDP. When enabled, it
"Enables the automatic disable of the Master Clock of the USB Device
Port when a suspend condition occurs". We fix the index to the real UDP
id which "Enables the 48 MHz clock of the USB Device Port".
