accel/ivpu: Split IP and buttress code

The NPU device consists of two parts: NPU buttress and NPU IP.
Buttress is a platform specific part that integrates the NPU IP with
the CPU.
NPU IP is the platform agnostic part that does the inference.

This separation enables support for multiple platforms using
a single NPU IP, so for example NPU IP 37XX could be integrated into
MTL and LNL platforms.
