Implemented Zhaoxin rng driver to add support for Zhaoxin HW RNG.
Both Zhaoxin-rng and via-rng rely on the XSTORE feature,
but the actual implementation is different. So add Vendor ID/Family
restrictions in via-rng module.

v1->v2:
    * Modify via-rng in a separate patch.
    * Fix some formatting issues.

leoliu-oc (2):
  hwrng: via-rng: convert to x86_cpu_id probing
  hwrng: add Zhaoxin HW RNG driver
