Merge branch 'clk-hw-register' (early part) into clk-next

* 'clk-hw-register' (early part):
  clk: fixed-rate: Add hw based registration APIs
  clk: gpio: Add hw based registration APIs
  clk: composite: Add hw based registration APIs
  clk: fractional-divider: Add hw based registration APIs
  clk: fixed-factor: Add hw based registration APIs
  clk: mux: Add hw based registration APIs
  clk: gate: Add hw based registration APIs
  clk: divider: Add hw based registration APIs
  clkdev: Add clk_hw based registration APIs
  clk: Add clk_hw OF clk providers
  clk: Add {devm_}clk_hw_{register,unregister}() APIs
  clkdev: Remove clk_register_clkdevs()
