EXYNOS: Convert Assembly code to c and make it common

Convert the assembly code in board/samsung to c and move the same to arch/arm. lds file made common across SMDKV310, Origen and SMDK5250.
Add the power reset and exit wakeup api for exynos.
Initialise GPIO for uart in Origen and SMDKV310 using pinmux.

Changes in V2:
- Rebased on latest u-boot-samsung tree.
- Incorporated review comments from Simon glass and Minkyu Kang.
Changes in V3:
- Optimised the mem_ctrl_init function for exynos4.
- Removed magic numbers.
Changes in V4:
- Used samsung_get_base api instead of hardcoding base address.
