Stephen Boyd b3ee3eff57 clk: qcom: Add simple regmap based muxes
Add support for muxes that use regmap instead of readl/writel
directly. We don't support as many features as clk-mux.c, but
this is good enough to support getting and setting parents.
Adding a table based lookup can be added in the future if needed.
