clk: mediatek: Disable tuner_en before change PLL rate
PLLs with tuner_en bit, such as APLL1, need to disable
tuner_en before apply new frequency settings, or the new frequency
settings (pcw) will not be applied.
The tuner_en bit will be disabled during changing PLL rate
and be restored after new settings applied.
Fixes: e2f744a82d725 (clk: mediatek: Add MT2712 clock support)
