Subject: [PATCH] USB: serial: option: add FOXCONN vendor and T99W368/T99W373  product

With the increase of the number of Foxconn devices, we add
a vendor name for Foxconn. The difference of T99W368 and
T99W373 is the chip solution. T99W368 is designed based
on Qualcomm SDX65 and T99W373 is SDX62.

Both of them share the same port configuration:
0&1: MBIM, 2: Modem, 3:GNSS, 4:NMEA, 5:Diag
GNSS port don't use serial driver.
