The currently assigned IRQ number to the OHCI
controller is incorrect for the AR7240 SoC, and
that leads to the following error message from
the OHCI driver:

ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver
ath79-ohci ath79-ohci: Atheros built-in OHCI controller
ath79-ohci ath79-ohci: new USB bus registered, assigned bus number 1
ath79-ohci ath79-ohci: irq 14, io mem 0x1b000000
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 1 port detected
usb 1-1: new full-speed USB device number 2 using ath79-ohci
ath79-ohci ath79-ohci: Unlink after no-IRQ?  Controller is probably using the 
wrong IRQ.

Fix this by using the correct IRQ number.
