ARM boards should use the generic GPIO API
This means changing gpio to unsigned type
Remove the unused gpio_toggle() function which is not part of the API
Comment that free should not modify pin state

gpio_free() should not have the side effect of setting the line to input since this prevents the gpio command from being able to set a line as output.

Convert all OMAP specific functions to use the common API
definitions in include/asm/gpio.h. In the process, made
few additional changes:
- Use -EINVAL consistently. -1 was used in many places.
- Removed one-liner static functions that were used only
once. Replaced the content as necessary.
- Combines implementation of functions omap_get_gpio_dataout()
and omap_get_gpio_datain(). To do so, new static function
_get_gpio_direction() was added.

The purpose of this patch is to prepare for adding the OMAP4 architecture, which is Cortex A9
Cortex A8 and A9 both belong to the armv7 architecture, hence the name change.
The two architectures are similar enough that substantial code can be shared.

Port version 2.6.27 of the linux kernel's omap gpio interface to u-boot.
The orignal source is in linux/arch/arm/plat-omap/gpio.c
See doc/README.omap3 for instructions on use.
