ARM: plat-iop: instantiate GPIO from platform device
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.
