f6ae1ca058 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

8475c869c3 s5p: gpio: change gpio coding method for s5p gpio.
Old s5p gpio coding method was not clean and was not working properly
for all parts and banks. New method is clean and easy to extend.

Gpio coding mask:
0x000000ff - pin number
0x00ffff00 - bank offset
0xff000000 - part number

7324907082 arm:mmc:goni/exynos: Fix wrong mmc base register devices offset.
On s5pc1xx mmc devices offset is multiply of 0x100000,
wrong value was 0x10000. Register offset always points
to mmc 0 before this change.

Add macro definition of mmc dev register offset to s5pc1xx and
exynos mmc.

ef5d9eb925 gpio:samsung s5p_ suffix add for GPIO functions
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).
