There's not much reason to have multiple fixed-factor-clock instances
which are all the same factor and clock input. Drop the nodes, but keep
the labels to minimize the changes and keep some distinction of the
different clocks.

I put patch 1/2 into the SoC patchwork:
https://patchwork.kernel.org/project/linux-soc/patch/20240627-arm-dts-fixes-v1-1-40a2cb7d344b@linaro.org/

I think Sudeep probably want to pick up patch 2/2 so as to avoid
conflicts.

Yours,
Linus Walleij
