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.

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.

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.
