Above this we have commit bdc3bbdd40ba ("clk: qcom: Clear hardware clock
control bit of RCG") that clears this bit. Is it possible to always set
this bit and then have an override flag used in sdm845 that says to
_not_ set this bit? Presumably on earlier platforms writing the bit is a
no-op so it's safe to write the bit on those platforms.
This way, if it's going to be the default we can avoid setting the flag
and only set the flag on older platforms where it shouldn't be done for
some reason.
