soc/mediatek/mt8192: pmic: update initial setting
We found that the switch frequency of vgpu is at 4~5Mhz with high
current case (> 3.5A) and is at 2.5Mhz with low current case(< 2.8A).
The switch frequency of vgpu should be kept at 2.5Mhz.
The root cause is that phase config of vcore is not disabled, it will
affect the switch frequency of vgpu. Corret the phase setting at
initialization.
