accel/ivpu: Use generation based function and registers names

Given that VPU generation can be used by multiple platforms, driver should
use VPU IP generation names instead of a platform.

Change naming for functions and registries.

Use 37XX format, where:
  3 - major VPU IP generation version
  7 - minor VPU IP generation version
  XX - postfix indicating this is an architecture and not marketing name
