This patch adds support for software I2C for GONI and Universal C210 reference targets.
It adds support for access to GPIOs by number, not as it is present,
by bank and offset.

This change is driven by need of general gpio_* functions,
which as their parameter are accepting the GPIO pin number, NOT
block and pin.
This makes the code alike to omap, and allows for using more
generic frameworks (e.g. software I2C).

Typically we declare the name of gpio structure to "gpio",
so it was duplicated around the name. (e.g: gpio->gpio_a)
This patch modified the naming that is removing "gpio_".

Because of s5pc1xx gpio is same as s5p seires SoC,
move gpio functions to drvier/gpio/
and modify structure's name from s5pc1xx_ to s5p_.

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.
