Add support for Zhaoxin hardware random number generator.
This driver base on rep_xstore instruction and uses the same
X86_FEATURE_XSTORE as via-rng driver. Therefore, modify the x86_cpu_id
array in the via-rng driver, so that the corresponding driver can be
correctly loader on respective platforms.

v1 -> v2:
1. Fix assembler code errors
2. Remove redundant CPU model check codes
