Revert "clk: versal: Enable clock driver for Versal NET"

This partially reverts commit ff332278.

Versal NET clock node should use "xlnx,versal-net-clk", "xlnx,versal-clk"
compatible string that's why it is not necessary to define Versal NET
specific compatible string if there is no any other change needed. It can
be get back if there is a need to differentiate clock support between
Versal and Versal NET.
