acer-wmi: support Lenovo ideapad S205 wifi switch
commit 15b956a0b5651bbb1217ec374fdd67291dabb2af upstream. 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.
