USB: serial: ftdi_sio: add support for u-blox EVK-M101

commit 2d8ab771d5316de64f3bb920b82575c58eb00b1b upstream.

The U-Blox EVK-M101 enumerates as 1546:0506 [1] with four FTDI interfaces:
- EVK-M101 current sensors
- EVK-M101 I2C
- EVK-M101 UART
- EVK-M101 port D

Only the third USB interface is a UART. This change lets ftdi_sio probe
the VID/PID and registers only interface #3 as a TTY, leaving the rest
available for other drivers.
