gpio: msm: Remove unused driver

Remove this driver now that Bjorn has introduced a pinctrl driver
for msm8660 and the dts files have been updated with the pinctrl
compatibles.

-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>;
