This seems to open a bisection hole. I see that ACLK is used in the
existing dtsi file, and that is the same as CLK_CPU, but after this
patch it will change to not exist anymore. Can we leave ACLK around
defined to be 0? I imagine it won't be used in the future so we can
remove it later. I can then apply this for v5.11-rc1 and then merge the
clk driver patch in clk tree.
