Merge branches 'clk-doc', 'clk-more-critical', 'clk-meson' and 'clk-basic-be' into clk-next

- Remove clk_readl() and introduce BE versions of basic clk types

* clk-doc:
  clk: Drop duplicate clk_register() documentation
  clk: Document and simplify clk_core_get_rate_nolock()
  clk: Remove 'flags' member of struct clk_fixed_rate
  clk: nxp: Drop 'flags' on fixed_rate clk macro
  clk: Document __clk_mux_determine_rate()
  clk: Document CLK_MUX_READ_ONLY mux flag
  clk: Document deprecated things
  clk: Collapse gpio clk kerneldoc

* clk-more-critical:
  clk: highbank: Convert to CLK_IS_CRITICAL
