x86/cpu: Create Zhaoxin processors architecture support file
Add x86 architecture support for new Zhaoxin processors.
Carve out initialization code needed by Zhaoxin processors into
a separate compilation unit.
To identify Zhaoxin CPU, add a new vendor type X86_VENDOR_ZHAOXIN
for system recognition.
