Subject: [PATCH v4 2/6] dt-bindings: mfd: Add lm36274 bindings to ti-lmu

Add the LM36274 backlight driver with regulator support.
This is a multi-function device for backlight applications.

Backlight properties will be documented in it's a supplemental
bindings document.

Regulator support is documented in the regulator/lm363x-regulator.txt
