We missed out the clock operation handling patch (Commit 16ada730a759)
and did not handle the clk_ops for Keem Bay SOC devices.
These 2 patches (Commit 16ada730a759) and (Commit 36c6aadaae86) are merged at around the same time.
We catch the issue later when trying to boot into v5.10-rc1 with Keem Bay EVM.
That is why I created this patch to handle the clk_ops for Keem Bay devices.

This is to fix issue on previous commit. It is a bug fix.
