[GIT PULL] clk: at91: clk changes for 5.16

Stephen,

Here are the clk changes for 5.16. I took the initiative to create a
Pull-Request for it as it's surely more convenient, as I proposed in my
reply to Claudiu's cover letter.
I created it on top of your current clk-at91 branch that contains one patch by
Clément already.

Please pull.

Thanks, best regards,
  Nicolas

The following changes since commit c405f5c15e9f6094f2fa1658e73e56f3058e2122:

  clk: at91: check pmc node status before registering syscore ops (2021-10-07 20:47:47 -0700)

  clk: use clk_core_get_rate_recalc() in clk_rate_get() (2021-10-21 14:00:59 +0200)

----------------------------------------------------------------
AT91 clk driver changes for 5.16:

- Clock power management for new SAMA7G5 SoC;
- Updates to the master clock driver and sam9x60-pll to be able to use
  cpufreq-dt driver and avoid overclocking of CPU and MCK0 domains while
  changing the frequency via DVFS;
- Power management refinement with the use of save_context()/restore_context()
  on each clock driver to specify their use in case of Backup mode only.

----------------------------------------------------------------
