Patch to add Curitel HX-550C USB modem support

[Maxim Azarov]

Hello! 
This patch adds support for Curitel HX-550C USB modem to 5.4 RELEASE.
(http://www.curitel.com/english/Product/cdma450/HX-550C.asp).
It solves the following problem with ucom when attaching device and
enables to use ucom0 as modem (I was able to work with SkyLink CDMA450
provider in Moscow, Russia with no problems after that using ppp):
---
May 15 07:22:35  kernel: ucom0: CURITEL Incorporated CURITEL HX-550C
USB Modem, rev 1.10/0.00, addr 2, iclass 2/2
May 15 07:22:35  kernel: ucom0: data interface 1, has CM over data, has break
May 15 07:22:40  kernel: ucom0: could not set data multiplex mode
May 15 07:22:40  kernel: device_attach: ucom0 attach returned 6
