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

-EXPERIMENTAL: The 16-sensors feature is marked EXPERIMENTAL because the
-implementation directly accesses hardware registers and may not work as
-expected. USE WITH CAUTION! To use this feature, you need to supply the
-experimental=1 parameter when loading the module. When EXPERIMENTAL
-mode is enabled, reading the first 8 sensors on newer ThinkPads will
-also use an new experimental thermal sensor access mode.
