OK, next attempt...

HID: expand hid-topseed driver to support 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.
