4.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Philipp Rossak <embe...@gmail.com>

commit b23af6ad8d2f708c4c3f92dd8f82c233247ba8bf upstream.

The eldoin is supplied from the dcdc1 regulator. The N_VBUSEN pin is
connected to an external power regulator (SY6280AAC).
With this commit we update the pmic binding properties to support
those features.
