platform/x86: asus-wmi: Fix spurious rfkill on UX8406MA
The Asus Zenbook Duo (UX8406MA) has a keyboard which can be
placed on the laptop to connect it via USB, or can be removed from the
laptop to reveal a hidden secondary display in which case the keyboard
operates via Bluetooth.

When it is placed on the secondary display to connect via USB, it emits
a keypress for a wireless disable. This causes the rfkill system to be
activated disconnecting the current wifi connection, which doesn't
reflect the user's true intention.

Detect this hardware and suppress any wireless switches from the
keyboard; this keyboard does not have a wireless toggle capability so
these presses are always spurious.
