Subject: [PATCH v3 06/10] clk: mediatek: clk-mt8195-topckgen: Register mfg_ck_fast_ref as generic mux

This clock was being registered as clk-composite through the helpers
for the same in the MediaTek clock APIs but, in reality, this isn't
a composite clock.

Appropriately register this clock with devm_clk_hw_register_mux().
No functional changes.
