	The Hygon Dhyana CPU has a topology extensions bit in CPUID. With this bit, the kernel can get the cache information. So add support in cpuid4_cache_lookup_regs() to get the correct cache size. The Hygon Dhyana CPU also discovers num_cache_leaves via CPUID leaf 0x8000001d, so add support to it in find_num_cache_leaves(). Also add cacheinfo_hygon_init_llc_id() and init_hygon_cacheinfo() functions to initialize Dhyana cache info. Setup cache cpumap in the same way as AMD does.

2018-09-27	x86/cpu: Create Hygon Dhyana architecture support file	Pu Wen
	Add x86 architecture support for a new processor: Hygon Dhyana Family 18h. Carve out initialization code needed by Dhyana into a separate compilation unit. To identify Hygon Dhyana CPU, add a new vendor type X86_VENDOR_HYGON. Since Dhyana uses AMD functionality to a large degree, select CPU_SUP_AMD which provides that functionality.
