Subject: [PATCH] platform/x86: thinkpad-acpi: Enable AMT by default on supported systems
Git-commit: 755b249250df1b612d982f3b702c831b26ecdf73
Patch-mainline: v6.0-rc1
References: bsc#1210050

By default the ACPI platform profile starts in balanced mode.
On supported systems AMT is supposed to be enabled in balanced
mode by default.

When checking the capabilities during initialization, set up AMT to be
enabled if it's supported.
