Move the 2 drivers from arch/mips/lantiq/xway/ to the subsystem and make them
buildable.

The following 2 patches will convert the drivers to OF.

The GE GPIO driver provides basic support (set direction, read/write state)
for the GPIO provided on some GE single board computers. This patch moves
the driver from the 86xx specific platform directrory to the GPIO subsystem
so that it can be used on non-86xx boards.

Sodaville has GPIO controller behind the PCI bus. To my suprissed it is
not the same as on PXA.

The interrupt & gpio chip can be referenced from the device tree like
from any other driver. Unfortunately the driver which uses the gpio
interrupt has to use irq_of_parse_and_map() instead of
platform_get_irq(). The problem is that the platform device (which is
created from the device tree) is most likely created before the
interrupt chip is registered and therefore irq_of_parse_and_map() fails.

In theory the driver works as module. In reality most of the irq
functions are not exported to modules and it is possible that _this_
module is unloaded while the provided irqs are still in use.

Move the driver to the place where it is expected to be nowadays. Also
rename its CONFIG-name to match the rest and adapt the defconfigs.
Finally, move selection of REQUIRE_GPIOLIB or WANTS_OPTIONAL_GPIOLIB to
the platforms, because this option is per-platform and not per-driver.

This patch adds support for Samsung GPIOs with one gpio driver
and removes old GPIO drivers which are drivers/gpio-s3c24xx.c,
gpio-s3c64xx.c, gpio-s5p64x0.c, gpio-s5pc100.c, gpio-s5pv210.c,
gpio-exynos4.c, gpio-plat-samsung.c, plat-samsung/gpio-config.c
and gpio.c to support each Samsung SoCs before. Because the
gpio-samsung.c can replace old Samsung GPIO drivers.
Basically, the gpio-samsung.c has been made by their merging
and removing duplicated definitions.

Note: gpio-samsung.c includes some SoC dependent codes and it
will be replaced next time.
