Márton Németh cd7bf8a554 gpio-pch: cleanup __iomem annotation usage
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)

Paul Gortmaker bb207ef1e8 drivers/gpio: Fix drivers who are implicit users of module.h
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.

Tomoya MORINAGA 2824bc9c38 gpio-pch: Use NUMA_NO_NODE not GFP_KERNEL
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.

Tomoya MORINAGA d4260e6ddd gpio-pch: modify gpio_nums and mask
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.
