media: si2168: add support for Mygica T230C v2
The T230C v2 hardware needs a mode of the si2168 chip to be set for which the si2168 driver previously had no support. This patch uses a specific measure to configure this on the T230C v2 hardware only - see the flag passed via the ts_mode attribute and its dependency on USB_PID_MYGICA_T230C2.
