Subject: [PATCH 3.16.y-ckt 071/165] usb: ftdi_sio: Add jtag quirk support for Cyber Cortex AV boards

3.16.7-ckt9 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Max Mansfield <max.m.mansfield@...il.com>

commit c7d373c3f0da2b2b78c4b1ce5ae41485b3ef848c upstream.

This patch integrates Cyber Cortex AV boards with the existing
ftdi_jtag_quirk in order to use serial port 0 with JTAG which is
required by the manufacturers' software.

Steps: 2

[ftdi_sio_ids.h]
1. Defined the device PID

[ftdi_sio.c]
2. Added a macro declaration to the ids array, in order to enable the
jtag quirk for the device.
