soc/mediatek/mt8188: Add PMIF and PMIC init support

Add PMIF, SPI, SPMI and PMIC init code.

These PMIC settings are used by MediaTek internally. We can find these
registers in "MT6365_PMIC_Data_Sheet_V1.4.pdf" and
"MT6315 datasheet v1.3.pdf". The setting values are provided by MeidaTek
designers.
