No, it's not a special node, but it's a very convenient one. It avoids
"crippling" the main SoC definition with all the clocks definition,
and keep the noise relatively low.

And a bunch of other maintainers seem to agree:
$ git grep "clocks {" -- arch/arm/boot/dts/ arch/arm64/boot/dts/ | wc -l
271
