Use struct drm_gem_shmem_object as a base for struct ivpu_bo.
This cuts by 50% the buffer management code.

VPU was rebranded as NPU (Neural Processing Unit) so user facing
strings have to be updated but the code remains as is and the module
is still called intel_vpu.ko.

Drivers that use the gen_pool*() family of functions should
select GENERIC_ALLOCATOR to prevent build errors like these:

VPU stands for Versatile Processing Unit and it's a CPU-integrated
inference accelerator for Computer Vision and Deep Learning
applications.
The VPU device consist of following components:
- Buttress - provides CPU to VPU integration, interrupt, frequency and
power management.
- Memory Management Unit (based on ARM MMU-600) - translates VPU to
host DMA addresses, isolates user workloads.
- RISC based microcontroller - executes firmware that provides job
execution API for the kernel-mode driver
- Neural Compute Subsystem (NCS) - does the actual work, provides
Compute and Copy engines.
- Network on Chip (NoC) - network fabric connecting all the components
This driver supports VPU IP v2.7 integrated into Intel Meteor Lake
client CPUs (14th generation).
Module sources are at drivers/accel/ivpu and module name is
"intel_vpu.ko".
This patch includes only very besic functionality:
- module, PCI device and IRQ initialization
- register definitions and low level register manipulation functions
- SET/GET_PARAM ioctls
- power up without firmware
