intel/compiler: Use gen_get_device_info() in test_eu_validate

intel/compiler: Use gen_get_device_info() in test_eu_validate

Previously the unit test filled out a minimal devinfo struct. A previous
patch caused the test to begin assert failing because the devinfo was
not complete. Avoid this by using the real mechanism to create devinfo.

Note that we have to drop icl from the table, since we now rely on the
name -> PCI ID translation done by gen_device_name_to_pci_device_id(),
and ICL's PCI IDs are not upstream yet.
