Subject: [PATCH] arm64: dts: rockchip: Add TPS65185 for PineNote

As the TPS65185 driver is now upsteram, add it to the PineNote devietrees.
This is based on https://ayakael.net/forge/linux-pinenote but modified to
the binding requirements.
Without any other out-of-tree materials applied, this enables the
hwmon temperature reporting and the interrupt counter increments
by one per reading.
