kernel: add package for Intel VPU/NPU driver

Intel NPU device is an AI inference accelerator integrated with Intel
client CPUs, starting from Intel Core Ultra generation of CPUs
(formerly known as Meteor Lake). It enables energy-efficient execution
of artificial neural network tasks.

The full device name is Neural Processing Unit, but the Linux kernel
driver uses the older name - Versatile Processing Unit (VPU).

This package is for NPU/VPU firmware.
