[3/4] clk: en7523: make pcie clk_ops accessible through of_device_id struct

Commit Message

Lorenzo Bianconi April 3, 2024, 4:20 p.m. UTC

Make pcie clk_ops structure accessible through of_device_id data
pointer in order to define multiple clk_ops for each supported SoC.
This is a preliminary patch to introduce EN7581 clock support.
