mb/google/asurada: revise PMIC and RTC initialization

Move the initialization from bootblock to romstage for following reasons:
- Follow MT8183 initialization sequence.
- PMIC and RTC functions are only called after verstage.
- Reduce bootblock size.
- PMIC initialization setting is complex and may need to be changed by
  an RW firmware update.

TEST=boot to kernel successfully
