It is important to note that the latter now belongs to Zhaoxin. Therefore, this patch replaces CPUID_VENDOR_VIA with CPUID_VENDOR_ZHAOXIN1. The previous CPUID_VENDOR_VIA macro was only defined but never used in QEMU, making this change straightforward. Additionally, the IS_ZHAOXIN_CPU macro has been added to simplify the checks for Zhaoxin CPUs.
