pinctrl: remove sirf atlas/prima drivers

The CSR SiRF prima2/atlas platforms are getting removed, so this driver
is no longer needed.

Documentation/devicetree/bindings/gpio/gpio-atlas7.txt

-CSR SiRFatlas7 GPIO controller bindings
-
-Required properties:
-- compatible	: "sirf,atlas7-gpio"
-- reg		: Address range of the pinctrl registers
-- interrupts	: Interrupts used by every GPIO group
-- gpio-banks	: How many gpio banks on this controller
-- gpio-controller : Indicates this device is a GPIO controller
-- interrupt-controller  : Marks the device node as an interrupt controller
-
-The GPIO controller also acts as an interrupt controller. It uses the default
-two cells specifier as described in Documentation/devicetree/bindings/
-interrupt-controller/interrupts.txt.
-
-Example:
-
-	gpio_0: gpio_mediam@17040000 {
-		compatible = "sirf,atlas7-gpio";
-		reg = <0x17040000 0x1000>;
-		interrupts = <0 13 0>, <0 14 0>;
-
-		#gpio-cells = <2>;
-		#interrupt-cells = <2>;
-
-		gpio-controller;
-		interrupt-controller;
-
-		gpio-banks = <2>;
-		gpio-ranges = <&pinctrl 0 0 0>,
-				<&pinctrl 32 0 0>;
-		gpio-ranges-group-names = "lvds_gpio_grp",
-					"uart_nand_gpio_grp";
-	};
-
-	leds {
-		compatible = "gpio-leds";
-
-		led1 {
-			gpios = <&gpio_1 15 0>;
-			...
-		};
-
-		led2 {
-			gpios = <&gpio_2 34 0>;
-			...
-		};
-	};
-

-gpio properties used by devices.

-CSR SiRFatlas7 pinmux controller
-
-Required properties:
-- compatible	: "sirf,atlas7-ioc"
-- reg		: Address range of the pinctrl registers
-
-For example, pinctrl might have properties like the following:
-	pinctrl: ioc@18880000 {
-			compatible = "sirf,atlas7-ioc";
-			reg = <0x18880000 0x1000>;
-

-				ac97 {
-					groups = "audio_ac97_grp";
-					function = "audio_ac97";
-				};
-			};
-
-			...
-
-			sd2_pmx: sd2@0 {
-				sd2 {
-					groups = "sd2_grp0";
-					function = "sd2";
-				};
-			};
-
-			...
-
-
-			sample0_cfg: sample0@0 {
-				sample0 {
-					pins = "ldd_0", "ldd_1";
-					bias-pull-up;
-				};
-			};
-
-			sample1_cfg: sample1@0 {
-				sample1 {
-					pins = "ldd_2", "ldd_3";
-					input-schmitt-enable;
-				};
-			};
-
-			sample2_cfg: sample2@0 {
-				sample2 {
-					groups = "uart4_nopause_grp";
-					bias-pull-down;
-				};
-			};
-
-			sample3_cfg: sample3@0 {
-				sample3 {
-					pins = "ldd_4", "ldd_5";
-					drive-strength = <2>;
-				};
-			};
-	};

-Please refer to pinctrl-bindings.txt in this directory for details of the common
-pinctrl bindings used by client devices.
-
-SiRFatlas7's pinmux nodes act as a container for an arbitrary number of subnodes.
-Each of these subnodes represents some desired configuration for a group of pins.
-
-Required subnode-properties:
-- groups : An array of strings. Each string contains the name of a group.
-- function: A string containing the name of the function to mux to the
-  group.
-
-  Valid values for group and function names can be found from looking at the
-  group and function arrays in driver files:
-  drivers/pinctrl/pinctrl-sirf.c
-
-For example, pinctrl might have subnodes like the following:
-	sd0_pmx: sd0@0 {
-		sd0 {
-			groups = "sd0_grp";
-			function = "sd0";
-		};
-	};
-
-	sd1_pmx0: sd1@0 {
-		sd1 {
-			groups = "sd1_grp0";
-			function = "sd1_m0";
-		};
-	};
-
-	sd1_pmx1: sd1@1 {
-		sd1 {
-			groups = "sd1_grp1";
-			function = "sd1_m1";
-		};
-	};
-
-For a specific board, if it wants to use sd1,
-it can add the following to its board-specific .dts file.
-sd1: sd@12340000 {
-	pinctrl-names = "default";
-	pinctrl-0 = <&sd1_pmx0>;
-}
-
-or
-
-sd1: sd@12340000 {
-	pinctrl-names = "default";
-	pinctrl-0 = <&sd1_pmx1>;
-}
