[PATCH v2 1/3] dt-bindings: leds: skyworks,aat1290: Document AAT1270 Current Regulator for Flash LEDs

[Svyatoslav Ryhel <clamor95@gmail.com>]

The AAT1270 Current Regulator for Flash LEDs has a similar configuration
to the AAT1290, but it uses a different programming model and requires a
separate compatible.
