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

Unlike Linux Kernel, U-Boot historically had *.dts files under
board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/.
I think arch/$(ARCH)/dts dicretory is a better location
to store both *.dts and *.dtsi files.
For example, before this commit, board/xilinx/dts directory
had both Microblaze dts (microblaze-generic.dts) and
ARM dts (zynq-*.dts), which are totally unrelated.
This commit moves *.dts to arch/$(ARCH)/dts/ directories,
allowing us to describe nicely mutiple DTBs generation in the next commit.

This adds clock references to the USB part of the device tree for U-Boot,
and marks USB1 as supporting legacy mode (which we disable in the driver).
The USB timing information may vary between boards sometimes, but for
now we hard-code it in C. This is because all current T2x boards use
the same values, we will deal with T3x later and we first need to agree
on the format for this timing information in the fdt and may in fact
decide that it has no place there.
