[PATCH v3 2/8] arm64: dts: rk3399-puma: fix gpio levels for vcc5v0-host regulator

From: Heiko Stuebner <heiko.stuebner at theobroma-systems.com>

The regulator enable-gpio uses opposite values for the declaration
vs. the enable_active_low property, breaking the regulator enablement.

Make the usbhost-supply work again by bringing them in sync again.

This mimics the upstream Linux change found on:
