The <mach/gpio.h> file is included from upper directories
and deal with generic GPIO and gpiolib stuff. Break out the
platform and driver specific defines and functions into its own
header file.

As per example from the other ARM boards, push the KS8695 GPIO
driver down to the GPIO subsystem so it can be consolidated.

Convert arch/arm includes of mach/gpio.h and asm/gpio.h to linux/gpio.h
before we start consolidating the individual platform implementations
of the gpio header files.

Convert to the new function names. Automated with coccinelle.

Use the GPIOlib .to_irq call to map KS8695 GPIOs
to the relevant IRQ line.

This patch is as small a change as possible to the KS8695 GPIO layer
to use GPIOLIB to allow the generic GPIO expanders and the like to
be compiled.

As a side-effect, we also remove __init_or_module from several
functions which could be called by drivers such as i2c-gpio which
could plausibly be compiled into a non-modular kernel.

Replace Macro names that have trailing underscores.
Also use the IOPD() macro instead of a hard-coded bit-shift (for
better readability).

This just leaves include/asm-arm/plat-* to deal with.

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

This patch adds a debug interface (if CONFIG_DEBUG_FS is selected) to

the Kendin/Micrel KS8695 processor.
