regulator: Updates for v7.0

Browse source 
There's a bunch of new drivers here, plus a lot of hardening for the
 supply resolution code which allow us to support systems where we have
 two PMICs each of which has regulators supplied by the other.  This did
 work a long time ago but got broken as part of improved integration with
 the device model, it's fairly rare so nobody noticed.
 
  - Improvements for supply handling from André Draszik to allow systems
    with two PMICs with supply/consumer relationships in both
    directions to instantiate.
  - New drivers for Maxim MAX776750, Realtek RT8902, Samsung S2MPG11,
    Texas Instuments TPS65185.
 
 This have also pulls in some MFD updates which are build dependencies
 for the Samsung S2MPG11 support.
