[PATCH] Add Zhaoxin x86 processor support

[DylanFan-oc]

Hi ，


These patches add the code to recognize three Zhaoxin processors(zxc, kx5000, kx6000).

The CPU Vendor ID "Shanghai" and "CentaurHauls" belongs to Zhaoxin and this part of

the code is maintained and upgraded by Zhaoxin now.


Please review and merge.
