[ARM] 3821/1: iop3xx: switch iop32x/iop33x over to shared pci code
Switch the iop32x and iop33x code over to the common PCI implementation, and remove the (nearly identical) iop32x and iop33x PCI implementations. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
