HID: add support for BTC Emprex 3009URF III Vista MCE Remote

The Behavior Tech. Computer Corp. (BTC) remote branded as "Emprex 3009URF III
Vista Remote Controller" uses non-standard mappings for all of its 'special
purpose' keys (0xffbc usage page).  This patch modifies the existing
hid-topseed quirky driver to support both remotes in order to prevent
proliferation of in-kernel quirky drivers until such a time that udev remapping
works with these devices.  Tested successfully with both the "Emprex" remote
and the "CyberLink" remote originally supported by the hid-topseed driver.
