Subject: [PATCH AUTOSEL 4.9 020/107] perf tools: Add Hygon Dhyana support

From: Pu Wen <puwen@...on.cn>

[ Upstream commit 4787eff3fa88f62fede6ed7afa06477ae6bf984d ]

The tool perf is useful for the performance analysis on the Hygon Dhyana
platform. But right now there is no Hygon support for it to analyze the
KVM guest os data. So add Hygon Dhyana support to it by checking vendor
string to share the code path of AMD.
