This adds standard device tree bindings for a reset GPIO line, and
the VDDD and VDDA power regulators.

Cc: devicetree@vger.kernel.org
Acked-by: Rob Herring <robh@kernel.org>

ChangeLog v3->v4:
- Just resending. If the old patch (in the tree) is good enough, just
  drop this.
ChangeLog v2->v3:
- None, just resending in case Jonathan prefers this binding doc
ChangeLog v1->v2:
- Order compatible string on single lines
- Add "bosch,bme280" for the new sensor from Matt
