The __iomem annotation is to be used together with pointers used
as iowrite32() parameter. For more details see [1] and [2].
This patch will remove the following sparse warnings ("make C=1"):
* warning: incorrect type in assignment (different address spaces)
* warning: incorrect type in argument 1 (different address spaces)
* warning: incorrect type in argument 2 (different address spaces)

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore. Make sure the modular drivers in gpio
are actually calling out for <module.h> explicitly in advance.

Currently, GFP_KERNEL is used as parameter of irq_alloc_descs like below.
irq_base = irq_alloc_descs(-1, IOH_IRQ_BASE, num_ports[j],
GFP_KERNEL);
This is not true.
So, this patch uses NUMA_NO_NODE not GFP_KERNEL.

Currently, when suspend is occurred, register im0/1 and gpio_use_sel are not
saved.
This patch modifies so that register im0/1 and gpio_use_sel are saved.

Currently, the number of GPIO pins is set fixed value(=12).
Also PIN MASK is set as '0xfff'.
However the pins differs by IOH.
This patch sets the value correctly.

Sort the gpio makefile and enforce the naming convention gpio-*.c for
gpio drivers.
v2: cleaned up filenames in Kconfig and comment blocks
v3: fixup use of BASIC_MMIO to GENERIC_GPIO for mxc
