ACPI: thinkpad-acpi: make EC-based thermal readings non-experimental

[Henrique de Moraes Holschuh <hmh-N3TV7GIv+o9fyO9Q7EP/yw@public.gmane.org>]

Reading the 16 thermal sensors directly from the EC has been stable for
about one year, in all supported ThinkPad models.  Remove its
"experimental" label.
