clk: mediatek: clk-mt8192: Add clock mux notifier for mfg_pll_sel

Browse source

Following the changes that were done for mt8183, add a clock notifier
for the GPU PLL selector mux: this allows safe clock rate changes by
temporarily reparenting the GPU to a safe clock (clk26m) while the
MFGPLL is reprogrammed and stabilizes.
