Input: synaptics-rmi4 - add parameters for dribble packets and palm detect gesture

The rmi_f11 driver currently disables dribble packets and the palm detect
gesture for all devices. This patch creates a parameter in the 2d sensor
platform data for controlling this functionality on a per device basis.

For more information on dribble packets:
Commit 05ba999fcabb ("HID: rmi: disable dribble packets on Synaptics
touchpads")

For more information on the palm detect gesture:
Commit f097deef59a6 ("HID: rmi: disable palm detect gesture when present")
