S5P: Exynos: Add GPIO pin numbering and rename definitions
This patch includes following changes :
* Adds gpio pin numbering support for EXYNOS SOCs.
To have consistent 0..n-1 GPIO numbering the banks are divided
into different parts where ever they have holes in them.
* Rename GPIO definitions from GPIO_... to S5P_GPIO_...
These changes were done to enable cmd_gpio for EXYNOS and
cmd_gpio has GPIO_INPUT same as s5p_gpio driver and hence
getting a error during compilation.
* Adds support for name to gpio conversion in s5p_gpio to enable
gpio command EXYNOS SoCs. Function has been added to asm/gpio.h
to decode the input gpio name to gpio number.
Example: SMDK5420 # gpio set gpa00
