platform/x86: thinkpad-acpi: Enable AMT by default on supported systems

Browse Source 
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.
