arm64: dts: imx8mn: remove GPU power domain reset

Browse Source 
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.
