regulator: tps6586x: add support for SYS rail
Device have SYS rail which is always ON. It is system power bus. LDO5
and LDO_RTC get powered through this rail internally. Add support for
this rail and make the LDO5/LDO_RTC supply by it. Update document
accordingly.
[swarren: Instantiate the sys regulator from board-harmony-power.c to
avoid regression.]
