This series covers the addition of the Audio PLL clock found on AT91 SoCs like
the SAMA5D2.
I also added the use of these clocks by the ClassD audi amplifier in both SoC
and board DT.

The Audio PLL is described in the sama5d2 datasheet chapter "29.8 Audio PLL".

Even if "it works" (!), note that I'm not satisfied with the current code and
would need some advice from people more accustomed with the CCF and
particularly composite audio PLL/clocks like these. For example, I do not take
into account the limits of these clocks (as described in the datasheet) and the
dependency between the PAD and the PMC child clocks.

Thanks in advance for your inputs.

Best regards,
  Nicolas
