clk: mstar: MStar/SigmaStar MPLL driver This adds a basic driver for the MPLL block found in MStar/SigmaStar ARMv7 SoCs. Currently this driver is only good for calculating the rates of it's outputs and the actual configuration must be done before the kernel boots. Usually this is done even before u-boot starts. This driver targets the MPLL block found in the MSC313/MSC313E but there is no documentation this chip so the register descriptions for the another MStar chip the MST786 were used as they seem to match.
