dt-bindings: input: convert syna,rmi4 to DT schema

Convert the bindings for Synaptics RMI4 bus and devices to DT schema.
Changes during conversion:
1. Add reset-gpios already used in DTS and mentioned by RMI4
   specification.
2. Do not require address/size cells, because without functions
   (children) they aren't really needed.

-Synaptics RMI4 2D Sensor Device Binding
-
-The Synaptics RMI4 core is able to support RMI4 devices using different
-transports and different functions. This file describes the device tree
-bindings for devices which contain 2D sensors using Function 11 or
-Function 12. Complete documentation for transports and other functions
-can be found in:
-Documentation/devicetree/bindings/input/rmi4.
-
-RMI4 Function 11 and Function 12 are for 2D touch position sensing.
-Additional documentation for F11 can be found at:
-http://www.synaptics.com/sites/default/files/511-000136-01-Rev-E-RMI4-Interfacing-Guide.pdf

-Optional Touch Properties:
-Description in Documentation/devicetree/bindings/input/touchscreen
-- touchscreen-inverted-x
-- touchscreen-inverted-y
-- touchscreen-swapped-x-y
-- touchscreen-x-mm
-- touchscreen-y-mm
-
-Optional Properties:
-- syna,clip-x-low: Sets a minimum value for X.
-- syna,clip-y-low: Sets a minimum value for Y.
-- syna,clip-x-high: Sets a maximum value for X.
-- syna,clip-y-high: Sets a maximum value for Y.
-- syna,offset-x: Add an offset to X.
-- syna,offset-y: Add an offset to Y.
-- syna,delta-x-threshold: Set the minimum distance on the X axis required
-				to generate an interrupt in reduced reporting
-				mode.
-- syna,delta-y-threshold: Set the minimum distance on the Y axis required
-				to generate an interrupt in reduced reporting
-				mode.
-- syna,sensor-type: Set the sensor type. 1 for touchscreen 2 for touchpad.
-- syna,disable-report-mask: Mask for disabling posiiton reporting. Used to
-				disable reporting absolute position data.
-- syna,rezero-wait-ms: Time in milliseconds to wait after issuing a rezero
-				command.

-Example of a RMI4 I2C device with F11:
-Example:
-	&i2c1 {
-		rmi4-i2c-dev@2c {

-http://www.synaptics.com/sites/default/files/511-000136-01-Rev-E-RMI4-Interfacing-Guide.pdf
-
-Optional Properties:
-- syna,nosleep-mode: If set the device will run at full power without sleeping.
-			nosleep has 3 modes, 0 will not change the default
-			setting, 1 will disable nosleep (allow sleeping),
-			and 2 will enable nosleep (disabling sleep).
-- syna,wakeup-threshold: Defines the amplitude of the disturbance to the
-				background capacitance that will cause the
-				device to wake from dozing.
-- syna,doze-holdoff-ms: The delay to wait after the last finger lift and the
-				first doze cycle.
-- syna,doze-interval-ms: The time period that the device sleeps between finger
-				activity.
