regulator: tps65911: Add new chip version

Browse Source 
The tps65911 chip introduces new features, including changes in
the regulator module.

- VDD1 and VDD2 remain unchanged.
- VDD3 is now named VDDCTRL and has a wider voltage range.
- LDOs are now named LDO1...8 and voltage ranges are sequential,
  making LDOs easier to handle.
