[PATCH] ARM: dts: i.MX8MP: disable NPU node if hardware is missing

[Holger Assmann <h.assmann@pengutronix.de>]

Besides its power domain, the NPU node itself also needs to be disabled
in the kernel device tree if no respective hardware is present at the
SoC.

The power domain has already been dealt with by upstream commit
924101c81d6e ("ARM: i.MX8MP: add feature controller support for Plus").
This patch adds the necessary entry for the NPU node.
