Subject: [RESEND 4/4 v7] arm64: dts: rockchip: add rk817 chg to Odroid Go Advance

From: Chris Morgan <macromorgan@...mail.com>

Add the new rk817 charger driver to the Odroid Go Advance. Create a
monitored battery node as well for the charger to use. All values
from monitored battery are gathered from the BSP kernel for the
Odroid Go Advance provided by HardKernel.
