x86/xen: Add Hygon Dhyana support to Xen
To make Xen work on the Hygon platform, reuse AMD's Xen support code path for Hygon Dhyana CPU. There are six core performance events counters per thread, so there are six MSRs for these counters. Also there are four legacy PMC MSRs, they are aliases of the counters. In this version, use the legacy and safe version of MSR access. Tested successfully with VPMU enabled in Xen on Hygon platform by testing with perf.
