With the introduction of downstream Linux 6.6, the iMX8MP VPU block
control node in DTS was renamed "blk-ctl@38330000" and will not match
the ones found in `node_path_imx8mp` resulting in the node not being
disabled on the VPU-less variants.

Add an extra node_path entry for imx8mp VPU block control that match
with downstream Linux.
