[v2,0/2] Slightly improve hardware description of Pine64 RockPro64

This is a small series that introduces small improvements to the way
Pine64 RockPro64 [1] single-board-computer is described in the DT files.
This applies to both production-run revisions of the RockPro64.

The introduced improvements boil down to eliminating some warnings from
the kernel log, by adding a previously undefined regulator and by adding
some previously missing references to the regulators.

The patch 2/2 also results in reliability improvements, by reportedly
resolving (some of) the longstanding issues resulting from using certain
PCI Express cards with the Pine64 RockPro64.

Changes in v2:
  - Dissolved the patch 2/2 notes into its description, according to the
    numerous power cycling/rebooting tests performed on a Pine64 RockPro64
    by @ChriChri and reported in the #rock64 channel on irc.pine64.org
  - Adjusted the cover letter to match the latest test results
  - Added "Fixes" and "Cc: stable" tags to both patches in the series
  - Added "Tested-by" to the patch 2/2, thanks to Chris' testing [2]
  - Added a few "Cc" tags to the patch 2/2, to make sure people involved
    in the earlier related patch [3] are in the loop
