clk: qcom: Revert sync_state based clk_disable_unused

Revert the postponement of clk_disable_unused() for clock providers that
implement sync_state, and the change to drivers implementing this, until
agreement on the implementation has been reached.

This reverts:
29e31415 ("clk: qcom: Remove need for clk_ignore_unused on sc8280xp")
99c0f7d3 ("clk: qcom: sdm845: Use generic clk_sync_state_disable_unused callback")
26b36df7 ("clk: Add generic sync_state callback for disabling unused clocks")
