HID: hid-mosart: support suspend/resume 



The device has 2 modes. The first one is an emulation of a touchscreen
by sending left and right button, and the second mode is the one used in
dual-touch (sending trackingID, touch and else).

In case of a suspend/resume, the device switch back to the first mode
described above (with left and right buttons).
This adds a hook in .reset_resume for the device to be switched to
the correct mode (I just copied the code in mosart_probe).
