Note that a corresponding definition does already exist in rk3568.dtsi.
That one *could* inherit the base definition and only override the
"pm_qos" property, but looking back to the original patch series it
seems like not doing that was a deliberate choice.

OK, my bad. I overlooked that both rk3566 and rk3568 have their
definition in their dtsi files, so there is no need for this patch.
Sorry for the confusion!
