HID: remove compat stuff

This removal was scheduled and there is no problem with later
distros to adapt for the new bus, thanks to aliases.

module-init-tools map files are deprecated nowadays, so that
the patch which introduced hid ones into the m-i-t won't be
accepted and hence there is no reason for leaving compat stuff in.
