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".
