mb/google/rex: Enable VPU device for Rex/Ovis baseboard
This patch enables the Versatile Processing Unit (VPU) by default for
Rex/Ovis baseboard. VPU is a dedicated AI engine that is included in
the 14th generation "Meteor Lake" Core processors.
The VPU is designed to efficiently run AI models directly on the
system on chip (SoC). There is no power regression observed while
keeping the VPU default enabled to run AI models natively hence, this
patch enables the VPU by default.
BUG=b:332488817
TEST=Able to see VPU PCI device in lspci (0:11:0) list after booting
google/screebo to OS.
