Clk documentation updates

Here's a random collection of core clk documentation updates. During the process I noticed that the 'flags' member of the fixed rate clk wasn't used, so I dropped it and updated the user in the NXP driver. I'm planning to apply this for the v5.2 series.

Stephen Boyd (8):
clk: Collapse gpio clk kerneldoc
clk: Document deprecated things
clk: Document CLK_MUX_READ_ONLY mux flag
clk: Document __clk_mux_determine_rate()
clk: nxp: Drop 'flags' on fixed_rate clk macro
clk: Remove 'flags' member of struct clk_fixed_rate
clk: Document and simplify clk_core_get_rate_nolock()
clk: Drop duplicate clk_register() documentation
