Subject: [PATCH AUTOSEL 5.4 16/50] perf/x86/intel: Add Elkhart Lake support

From: Kan Liang <kan.liang@...ux.intel.com>

[ Upstream commit eda23b387f6c4bb2971ac7e874a09913f533b22c ]

Elkhart Lake also uses Tremont CPU. From the perspective of Intel PMU,
there is nothing changed compared with Jacobsville.
Share the perf code with Jacobsville.
