SMDK5250 board is based on Samsungs EXYNOS5250 SoC.

Signed-off-by: Chander Kashyap <chander.kashyap@linaro.org>
---
Changes for v2:
	- This patch is bifurcated into borad support and SoC support
	- Fixed typo: s/EEYNOS/EXYNOS
	- Squashed patch "SMDK5250: enable device tree support" in this.
Changes for v3:
	- None
Changes for v4:
	- Converted assembly routines for clock, memory, uart and tzpc
	- init to c functions
	- Moved uart init to smdk5250.c
Changes for v5:
	- Remove initof gpio1
	- Fixed gpio configuration for uart
Changes for v6:
	- Add gpio1 init in board_uart_init, which was removed in v5

Can't those be defined appropriately?
Splitting the function to several functions would make it
much more readable and nice (because currently it looks very ugly...).
Are all these writes board specific?
