gpio: Drop TZ1090 drivers

Now that arch/metag/ has been removed, along with TZ1090 SoC support,
remove the TZ1090 GPIO drivers. They are of no value without the
architecture and SoC platform code.

-ImgTec TZ1090 GPIO Controller
-
-Required properties:
-- compatible: Compatible property value should be "img,tz1090-gpio".
-
-- reg: Physical base address of the controller and length of memory mapped
-  region.
-
-- #address-cells: Should be 1 (for bank subnodes)
-
-- #size-cells: Should be 0 (for bank subnodes)
-
-- Each bank of GPIOs should have a subnode to represent it.
-
-  Bank subnode required properties:
-  - reg: Index of bank in the range 0 to 2.
-
-  - gpio-controller: Specifies that the node is a gpio controller.
-
-  - #gpio-cells: Should be 2. The syntax of the gpio specifier used by client
-    nodes should have the following values.
-       <[phandle of the gpio controller node]
-        [gpio number within the gpio bank]
-        [gpio flags]>
-
-    Values for gpio specifier:
-    - GPIO number: a value in the range 0 to 29.
-    - GPIO flags: bit field of flags, as defined in <dt-bindings/gpio/gpio.h>.
-      Only the following flags are supported:
-        GPIO_ACTIVE_HIGH
-        GPIO_ACTIVE_LOW
-
-  Bank subnode optional properties:
-  - gpio-ranges: Mapping to pin controller pins (as described in
-    Documentation/devicetree/bindings/gpio/gpio.txt)
-
-  - interrupts: Interrupt for the entire bank
-
-  - interrupt-controller: Specifies that the node is an interrupt controller
-
-  - #interrupt-cells: Should be 2. The syntax of the interrupt specifier used by
-    client nodes should have the following values.
-       <[phandle of the interurupt controller]
-        [gpio number within the gpio bank]
-        [irq flags]>
-
-    Values for irq specifier:
-    - GPIO number: a value in the range 0 to 29
-    - IRQ flags: value to describe edge and level triggering, as defined in
-      <dt-bindings/interrupt-controller/irq.h>. Only the following flags are
-      supported:
-        IRQ_TYPE_EDGE_RISING
-        IRQ_TYPE_EDGE_FALLING
-        IRQ_TYPE_EDGE_BOTH
-        IRQ_TYPE_LEVEL_HIGH
-        IRQ_TYPE_LEVEL_LOW

-Example:
-
-	gpios: gpio-controller@2005800 {
-		#address-cells = <1>;
-		#size-cells = <0>;
-		compatible = "img,tz1090-gpio";
-		reg = <0x02005800 0x90>;
-
-		/* bank 0 with an interrupt */
-		gpios0: bank@0 {
-			#gpio-cells = <2>;
-			#interrupt-cells = <2>;
-			reg = <0>;
-			interrupts = <13 IRQ_TYPE_LEVEL_HIGH>;
-			gpio-controller;
-			gpio-ranges = <&pinctrl 0 0 30>;
-			interrupt-controller;
-		};
-
-		/* bank 2 without interrupt */
-		gpios2: bank@2 {
-			#gpio-cells = <2>;
-			reg = <2>;
-			gpio-controller;
-			gpio-ranges = <&pinctrl 0 60 30>;
-		};
