clk: uniphier: add CPU-gear change (cpufreq) support

Browse source

Core support code for CPU frequency changes, which will be used by
the generic cpufreq driver.

The register view is different from the generic clk-mux; it has
a separate status register, and an update bit to load the register
setting.
