EXYNOS: Move files from board/samsung to arch/arm
This patch performs the following: 1) Convert the assembly code for memory and clock initialization to C code. 2) Move the memory and clock init codes from board/samsung to arch/arm 3) Creat a common lowlevel_init file across Exynos4 and Exynos5. Converted the common lowlevel_init from assembly to C-code 4) Made spl_boot.c and tzpc_init.c common for both exynos4 and exynos5. 5) Enable CONFIG_SKIP_LOWLEVEL_INIT as stack pointer initialisation is already done in _main. 6) exynos-uboot-spl.lds made common across SMDKV310, Origen and SMDK5250. TEST: Tested SD-MMC boot on SMDK5250 and Origen. Tested USB and SPI boot on SMDK5250 Compile tested for SMDKV310.
