x86/amd_nb: Fix northbridge init warning in guest for Hygon family 18h model 4h 

hygon inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBM2BF


CVE: NA

---------------------------

When booting in guest on Hygon family 18h model 4h platform, there
is warning as follows:
"Hygon Fam18h Model4h northbridge init failed(-19)!"

Avoid the northbridge init failure warning in guest since there is
no northbridge.

Fixes: fc02cdbf ("x86/amd_nb: Add northbridge support for Hygon family 18h model 4h")
