[PATCH] perf/x86/intel: Add hardware cache event support for Intel Gemini Lake

[Yunying Sun <yunying.sun@intel.com>]

Gemini Lake is a Goldmont core based Apollo Lake successor with better
CPU performance. Currently there is no hardware cache events available
if checking with "perf list cache" on Gemini Lake. Perf hardware cache
event test always fail because of this.

This patch adds INTEL_FAM6_ATOM_GEMINI_LAKE case to use same Goldmont
hardware cache events table for Gemini Lake. With this patch, below
hardware cache events are available on Gemini Lake, and perf hardware
cache event test can pass.
