This is the initial commit for the UniPhier clock drivers, including
support for PH1-sLD3, PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5, and
ProXstream2/PH1-LD6b.
To improve the code maintainability, the driver consists of common
functions (clk-uniphier-core.c) and clock data arrays needed to
support each SoC.
