gpio: iop: fix devm_ioremap_resource() return value checking devm_ioremap_resource() returns a pointer to the remapped memory or an ERR_PTR() encoded error code on failure. Fix the check inside iop3xx_gpio_probe() accordingly.

ARM: plat-iop: pass physical base for GPIO This alters the IOP platforms to pass a physical base for their GPIO blocks and alters the driver to remap it when probing instead of relying on the virtual addresses to be used.

gpio: iop: use readl/writel accessors Use the standard 32bit I/O accessors instead of just assigning addresses.

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.

ARM: plat-iop: remove custom complex GPIO implementation The kernel will now only use gpiolib to access GPIOs, so remove the complex GPIO flag and the custom implementation.

gpio: decouple the IOP GPIO driver from platform This removes the only dependence between the IOP GPIO driver and the GENERIC_GPIO header in <mach/gpio.h> and its common implementation in the <asm/*> namespace by copying the one constant it is using into the driver file.
