exynos: spl: Add a custom spi copy function
This patch implements a custom spi_copy funtion to copy u-boot from SF to RAM. This is faster then iROM spi_copy funtion as this runs spi at 50Mhz and also in WORD mode of operation. Changed a printf in pinmux.c to debug just to avoid the compilation error in SPL.
