acer-wmi: support Lenovo ideapad S205 wifi switch 

The AMW0 function in acer-wmi works on Lenovo ideapad S205 for control
the wifi hardware state. We also found there have a 0x78 EC register
exposes the state of wifi hardware switch on the machine.

So, add this patch to support Lenovo ideapad S205 wifi hardware switch
in acer-wmi driver.
