The armclk starts in slow mode (24MHz) on the rk3188, which makes the whole startup take a lot of time. We therefore want to at least move to the safe 600MHz value we can use with default pmic settings. This is also the freqency the proprietary sdram-init leaves the cpu at.
For boards that have pmic control later in u-boot, we also add the option to set the maximum frequency of 1.6GHz, if they so desire.
