HID: hid-multitouch: refactor initialization of ABS_MT_ORIENTATION

Browse Source 
The way the input_set_abs_params was called for the new composite field
ABS_MT_ORIENTATION was not very clear at second reading.  We can remove the
non-necessary call to set_abs and use the simple call to input_set_abs_params.
