This commit message does not match what this patch does. In this patch
you revert a change and in next patch you re-introduce same thing
slightly different.

As mentioned in v1, see [1], you should merge both patches as a single
fix, if a fix really is needed.

Testing on a rk3328-rock64 I see no difference before or after these
changes. Please describe what this fixes because clk_summary show same
clock tree and rates before and after this fix.

Also for next revert patch you send, please include the patch author in
the recipient list :-)
