acerhdf: limit modalias matching to supported

commit bdc731bc5fcd1794e9ac8ac80c389d302381c123 upstream.

BugLink: https://bugs.launchpad.net/ubuntu/+bug/435958

The module alias currently matches any Acer computer but when loaded the
BIOS checks will only succeed on Aspire One models.  This causes a invalid
BIOS warning for all other models (seen on Aspire 4810T).  This is not
fatal but worries users that see this message.  Limiting the moule alias
to models starting with AOA or DOA for Packard Bell.
