This converts the IOP32x and IOP33x platforms to pass their base address offset by a resource attached to a platform device instead of using static offset macros implicitly passed through <linux/gpio.h> including <mach/gpio.h>. Delete the local <mach/gpio.h> and <asm/hardware/iop3xx-gpio.h> headers and remove the selection of NEED_MACH_GPIO_H. Pass the virtual address as a resource in the platform device at this point for bisectability, next patch will pass the physical address as is custom.
