ARM: PCI: integrator: use common PCI swizzle
The Integrator swizzle function is almost the same as the standard PCI swizzle, except for an initial check for pin = 0. Make the integrator swizzle function a wrapper around the standard PCI swizzle function so we preseve this behaviour while using common code. [fix to use pci_std_swizzle from Linus Walleij] Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
