dell-laptop: Remove rfkill code
a6c2390cd6d2083d27a2359658e08f2d3df375ac
This patch causes some trouble with my dell laptop (Vostro 3300). It produces some annoying behaviour with the Wifi kill-switch.
As rfkill can not get the state of the physical kill-switch, both state may differ.
physical switch is OFF
rfkill state is ON
=> Laptop hangs on boot (maybe because a physical ascent device is used by network subsystem)
physical switch is OFF
rfkill state is OFF
=> Activate interface in Gnome Connection Manager => System hang
test setup:
Dell Vostro 3300
Broadcom 4313 Wifi
Kernel 3.5.[0-2] & 3.6
Fedora 17

Again this is an example for patches accepted in mainline without being tested on supported hardware :-(

b43 should know the state of the physical rfkill switch even if there's
no platform code to support it.

BCM 4313 is _only_ supported by BCMs proprietar driver and brcmsmac; and
the later one I use.
Further there should be problems with other Wifis, like Intel?

Ok, well definitely seems like a bug in brcmsmac.

Why?
