[PATCH] arm64: dts: imx8mn: remove GPU power domain reset

[Lucas Stach]

From: Marco Felsch <m.felsch at pengutronix.de>

The PGC (power gating controller) already handles the reset for the
GPUMIX power domain. By specifying it within the device tree the reset
it issued a 2nd time. This confuses the hardware during power up and
sporadically hangs the SoC. Fix this by removing the reset property and
let the hardware handle the reset.
