Vipul Kumar Samar 86605cfe8c gpio: stmpe: Add DT support for stmpe gpio
This patch allows the STMPE GPIO driver to be successfully probed and
initialised when Device Tree support is enabled. Bindings are mentioned in
Documentation too.

STMPE gpio
----------
Required properties:
- compatible: "st,stmpe-gpio"
Optional properties:
- st,norequest-mask: bitmask specifying which GPIOs should _not_ be requestable
due to different usage (e.g. touch, keypad)
Node name must be stmpe_gpio and should be child node of stmpe node to which it
belongs.
Example:
stmpe_gpio {
compatible = "st,stmpe-gpio";
st,norequest-mask = <0x20>; //gpio 5 can't be used
};
