Input: rename cap1106 driver to cap11xx

There are several devices in cap11xx family besides cap1106. The driver can
be made to support all of them, so let's give it more generic name.

+Device tree bindings for Microchip CAP11xx based capacitive touch sensors
+
+The node for this device must be a child of a I2C controller node, as the
+device communication via I2C only.
+
+Required properties:
+
+	compatible:		Must contain one of:
+					"microchip,cap1106"
+
+	reg:			The I2C slave address of the device.
+				Only 0x28 is valid.
+
+	interrupts:		Property describing the interrupt line the
+				device's ALERT#/CM_IRQ# pin is connected to.
+				The device only has one interrupt source.
+
+Optional properties:
+
+	autorepeat:		Enables the Linux input system's autorepeat
+				feature on the input device.
+
+	microchip,sensor-gain:	Defines the gain of the sensor circuitry. This
+				effectively controls the sensitivity, as a
+				smaller delta capacitance is required to
+				generate the same delta count values.
+				Valid values are 1, 2, 4, and 8.
+				By default, a gain of 1 is set.
+
+	linux,keycodes:		Specifies an array of numeric keycode values to
+				be used for the channels. If this property is
+				omitted, KEY_A, KEY_B, etc are used as
+				defaults. The array must have exactly six
+				entries.
+
+Example:
+
+i2c_controller {
+	cap1106@28 {
+		compatible = "microchip,cap1106";
+		interrupt-parent = <&gpio1>;
+		interrupts = <0 0>;
+		reg = <0x28>;
+		autorepeat;
+		microchip,sensor-gain = <2>;
+
+		linux,keycodes = <103>,		/* KEY_UP */
+				 <106>,		/* KEY_RIGHT */
+				 <108>,		/* KEY_DOWN */
+				 <105>,		/* KEY_LEFT */
+				 <109>,		/* KEY_PAGEDOWN */
+				 <104>;		/* KEY_PAGEUP */
+	};
+}
