regulator: tps6586x: Add support for the TPS658640

Browse Source 
The TPS658640 has a different set of output voltage for most LDO and
the RTC LDO isn't settable. This chip also report 2 different version
ID, as the datasheet doesn't list the possible values the second ID
has simply been named TPS658640v2.
