gpio: msm: Add device tree and irqdomain support for gpio-msm-v2
This cleans up the gpio-msm-v2 driver of all the global define usage. The number of gpios are now defined in the device tree. This enables adding irqdomain support as well.

+MSM GPIO controller bindings
+
+Required properties:
+- compatible:
+ - "qcom,msm-gpio" for MSM controllers
+- #gpio-cells : Should be two.
+ - first cell is the pin number
+ - second cell is used to specify optional parameters (unused)
+- gpio-controller : Marks the device node as a GPIO controller.
+- #interrupt-cells : Should be 2.
+- interrupt-controller: Mark the device node as an interrupt controller
+- interrupts : Specify the TLMM summary interrupt number
+- ngpio : Specify the number of MSM GPIOs
+
+Example:
+
+ msmgpio: gpio@fd510000 {
+ compatible = "qcom,msm-gpio";
+ gpio-controller;
+ #gpio-cells = <2>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ reg = <0xfd510000 0x4000>;
+ interrupts = <0 208 0>;
+ ngpio = <150>;
+ };
