Name the regulator as per board schematics and adds its
supply name info in regulator data.
Add the always on fixed regulator to refer the battery supply.

Use this fixed regulator for input supply of some of PMIC
regulator

Note that this file might well be deleted within the 3.7 development
cycle, since we will presumably get to the point where when booting from
DT, the DT will set up the regulators, and we won't support non-DT
booting any more on Harmony. Still, that should merge without issues, so
I don't think this will be a problem.
