ACPI: thinkpad-acpi: debug facility to emulate the rf switches
This code is required to keep the thinkpad-acpi maintainer sane, and
it is disabled by default.
Add a debug facility to simulate an rfkill hardware rocker switch, a
bluetooth rfkill soft-switch, a WWAN rfkill soft-switch on thinkpads.
The simulated switches obviously do not kill any radios in hardware or
firmware (unlike the real one). They also don't issue deprecated proc
events.
