ACPI: thinkpad-acpi: export to sysfs the state of the radio slider switch
Some ThinkPad models, notably the T60 and X60, have a slider switch to enable and disable the radios. The switch has the capability of force-disabling the radios in hardware on most models, and it is supposed to affect all radios (WLAN, WWAN, BlueTooth). Export the switch state as a sysfs attribute, on ThinkPads where it is available. Thanks to Henning Schild for asking for this feature, and for tracking down the EC register that holds the radio switch state.
