cover rfkill for tc1100-wmi

The following series implements rfkill support for tc1100-wmi, and rips out the old sysfs interface for wireless.

As I don't have the hardware, this is compile-tested only, so I'd appreciate some victims^^^^^^volunteers testing this first (and/ or possibly some time in linux-next).

PATCH 1/2 tc1100-wmi: Convert wireless to use rfkill

Removal of the old sysfs file will be left for a future patch.

Also, I don't own the hardware, so this patch is compile tested only (though mostly based on the working acer-wmi code).

While we're at it, fix the broken Kconfig description.

PATCH 2/2 tc1100-wmi: Remove wireless sysfs entry

In reply to Carlos Corbacho

With the addition of the rfkill interface, this is no longer required. Also, clean up the custom suspend/ resume handling for wireless while we're at it.
