Subject: USB: serial: Another Infineon flash loader USB ID

From: Jonas Jonsson <jonas@ludd.ltu.se>

commit a0e80fbd56b4573de997c9a088a33abbc1121400 upstream.

The flash loader has been seen on a Telit UE910 modem. The flash loader
is a bit special, it presents both an ACM and CDC Data interface but
only the latter is useful. Unless a magic string is sent to the device
it will disappear and the regular modem device appears instead.
