Revert "clk: qcom: regmap-phy-mux: Rework the implementation"

This reverts commit e108373c54fbc844b7f541c6fd7ecb31772afd3c.

This has been reported to break PCIe on at least SM8350 and Eliza
platforms. I had originally tested this on Hamoa (X1E) where there were
no adverse effects. It's highly likely that this stems from a
difference in how the bootloader configures the clocks.

Revert the offending change to fix the issue in the immediate, with the
intent to revisit it in the upcoming cycle.
