From: Vitor Soares <vitor.soares at toradex.com>

On imx8m[m|p|q].dtsi, upstream Linux uses different names for NPU/VPU
IP block nodes. It leads variants without such HW block having it
enabled by default.

This patch adds the upstream Linux node's paths to the disable list while
keep the compatibility with downstream Linux.
