asus-nb-wmi: add wapf quirk for ASUS machines
The BIOS of these machines will try to enable/disable wifi/bt in
their own sqeuence. It won't read the enable/disable parameter
in WMI command, but just iterates the wifi/bt's status described below
1st. enable wifi, enable bt
2nd. disable wifi, enable bt
3rd. enable wifi, disable bt
4th. disable wifi, disable bt
That will totally mess up the rfkill status, since we will try to read
wifi and bt's status and reset it again while booting up.
To avoid this, these machines should set the wapf value to 4,
that will let software totally control the wifi/bt's status and
BIOS will do nothing instead of sending out the 0x88(KEY_RFKILL) event
instead of 0x5e(wifi enable), 0x5f(wifi diable), 0x7d(bt enable), and
0x7e(bt disable) through WMI.
With this patch[1], it will handle the KEY_RFKILL event correctly and
will block/unblock wifi and bt together.
