Hygon Dhyana processor has the topology extensions bit in CPUID.
With this bit kernel can get the cache info. So add support

"With this bit, the kernel... "

in cpuid4_cache_lookup_regs() to get the correct cache size.

Dhyana also find num_cache_leaves via CPUID leaf 0x8000001d, so

"... also discovers num_cache_leaves ..."

add Hygon support 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.
