Subject: [PATCH 5.16 123/186] arm64: dts: imx8mm: Fix VPU Hanging

From: Adam Ford <aford173@...il.com>

[ Upstream commit ef3075d6638d3d5353a97fcc7bb0338fc85675f5 ]

The vpumix power domain has a reset assigned to it, however
when used, it causes a system hang.  Testing has shown that
it does not appear to be needed anywhere.

Fixes: d39d4bb15310 ("arm64: dts: imx8mm: add GPC node")
