Since commit d39d4bb15310 ("arm64: dts: imx8mm: add GPC node") the GW7901 will hang during kernel init because it does not power the unused GPU voltage rails on the IMX8MM. Disable pgc_gpumix to work around this.
We also disable the GPU devices that depend on the gpumix power domain to avoid them staying in a probe deferred state forever.
