clk: mxl: Switch from direct readl/writel based IO to regmap based IO
Earlier version of driver used direct io remapped register read
writes using readl/writel. But we need secure boot access which
is only possible when registers are read & written using regmap.
This is because the security bus/hook is written & coupled only
with regmap layer.
Switch the driver from direct readl/writel based register accesses
to regmap based register accesses.
Additionally, update the license headers to latest status.
