ARM: 7588/1: amba: create a resource parent registrator
This creates amba_apb_device_add_res() and amba_ahb_device_add_res() respectively, to add devices with another parent than iomem_resource. This is needed to specify that a device is contained in a specific IO range. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
