[PATCH] input: Add support for Rotronic silver/white handset in cm109 driver

[Georgi Chorbadzhiyski <gf@unixsol.org>]

cm109 driver. Rotronic silver/white is USB "Skype" handset
sold in Bulgaria and Serbia (according to Google). With this
cheap stuff a picture is the only way to identify what you've
got, so here is one:
