acer-wmi: replaced the hard coded bitmap by the communication devices bitmap from...

Before set communication devices state, we need query out all devices state to set
the states bitmap. That will be better use the devices bitmap in SMBIOS type Aah
instead of hardcode in driver.

Tested on Acer Travelmate 8572.
