Documentation: Describe bindings for STMPE Multi-Functional Device driver 

Here we add the required documentation for the STMPE Multi-Functional
Device (MFD) Device Tree bindings. It describes all of the bindings
currently supported by the driver.

* STMPE Multi-Functional Device
Required properties:
- compatible : "st,stmpe[811|1601|2401|2403]"
- reg : I2C address of the device
Optional properties:
- interrupts : The interrupt outputs from the controller
- interrupt-controller : Marks the device node as an interrupt controller
- interrupt-parent : Specifies which IRQ controller we're connected to
- i2c-client-wake : Marks the input device as wakable
- st,autosleep-timeout : Valid entries (ms); 4, 16, 32, 64, 128, 256, 512 and 1024
Example:
stmpe1601: stmpe1601@40 {
compatible = "st,stmpe1601";
reg = <0x40>;
interrupts = <26 0x4>;
interrupt-parent = <&gpio6>;
interrupt-controller;
i2c-client-wake;
st,autosleep-timeout = <1024>;
};
