Aaro Koskinen f5d6a1441a ARM: 7692/1: iop3xx: move IOP3XX_PERIPHERAL_VIRT_BASE 
Currently IOP3XX_PERIPHERAL_VIRT_BASE conflicts with PCI_IO_VIRT_BASE:

					address         size
	PCI_IO_VIRT_BASE                0xfee00000      0x200000
	IOP3XX_PERIPHERAL_VIRT_BASE     0xfeffe000      0x2000

Fix by moving IOP3XX_PERIPHERAL_VIRT_BASE below PCI_IO_VIRT_BASE.

The patch fixes the following kernel panic with 3.9-rc1 on iop3xx boards:
