Add x86 architecture support for a new processor: Hygon Dhyana Family 18h. To make Hygon initialization flow more clear, carve out code from amd.c into a separate file hygon.c, and remove unnecessary code for Hygon Dhyana. To identify Hygon Dhyana CPU, add a new vendor type X86_VENDOR_HYGON and vendor ID "HygonGenuine" for system recognition, and fit the new x86 vendor lookup mechanism. Hygon can fully use the function early_init_amd(), so make this common function non-static and direct call it from Hygon code. Add a separate hygon_get_topology(), which calculate phys_proc_id from AcpiId[6](see reference [1]).
