- Register offset fix for stmpe

Browse Source 
- Eradicate build warning when !PM in rtsx_pcr
  - Fix device ID collision when multiple boards are connected in viperboard
  - Use correct Regmap handle - fixing unhanded IRQs in max77693
  - Unmask MUIC IRQs in max77693
  - Clear VBUS & CHG bits so board doesn't reboot instead of poweroff in twl4030
