[PATCH 00/16] clk: at91: Rework DT bindings

[Alexandre Belloni]

This is the promised rework of the at91 PMC clocks driver. It is mainly
necessary to remove the DTC warnings but it also complies with the CCF
rule that there should be one node per controller instead of one node
per clock.

This only handles the PMC, I'm planning to also rework the SCKC bindings
later (without breaking the DT ABI).

The series is based on top of clk-next plus at91-dt so I don't think it
is convenient to have it this cycle. However, I would really like to
ensure we agree on the new bindings this cycle before converting all the
other platforms as this is a bit tedious.

The first two patches are actually fixes and may be considered for this
cycle.

One nice note:
at91-sama5d2_xplained.dtb goes from 29351 bytes to 22082 bytes

drivers/clk/at91/built-in.o changes that way:

   text	   data	    bss	    dec	    hex	
  34792	     24	    732	  35548	   8adc	before
  39438	     32	    741	  40211	   9d13	after
  28300	     32	    741	  29073	   7191	without dt-compat
