HID: multitouch: Add support for B2402FVA track point

By default the track point does not work on the Asus Expertbook B2402FVA.

From libinput record i got the ID of the track point device:
  evdev:
    # Name: ASUE1201:00 04F3:32AE
    # ID: bus 0x18 vendor 0x4f3 product 0x32ae version 0x100

I found that the track point is functional, when i set the
MT_CLS_WIN_8_FORCE_MULTI_INPUT_NSMU class for the reported device.
