exynos5420: Change some clock settings.
This change adjusts some clock settings so that they match U-Boot. There are three different changes. 1. Change the source for psgen from the oscillator clock to the pclk. 2. Change the pll feeding the SPI busses from epll to mpll, as suggested in the manual. 3. Change the SPI prescaller.
