Enable reboot driver for the X-Gene platform. Add generic syscon reboot
driver.

V9 Change:
	- rebase on Guenter Roeck's V5 reset handler patch set. This 
	  allows for a generic reset to be call rather than the arm
	  specific reset handler.

V8 Change:
	- change Kconfig to depend on ARM || ARM64 || COMPILE_TEST

V7 Change:
	- Seem V3 on, the patches were not making in to the mailinglist.
	- Fix build error produced by other ARCH while including this
	  driver. Set to depend on arm64 ARCH for now.

V6 Change:
	- Add documentation for scu node.

V5 Change:
	- Documentation update, endian and access size.

V4 Change:
	- Remove old X-Gene reboot driver
	- Add generic syscon reboot driver
	- Add DTS and Kconfig for X-Gene reboot using syscon method

V3 Change:
	- Remove the reboot driver's use of acpi resource patch.
	- Change the reboot driver to use syscon to parse out 
	  system clock register. Remove the old method of getting
	  register from the reboot driver directly.
	- Remove documentation since its now simple.

V2 Change:
	- Add support for using ACPI resource.

+Generic SYSCON mapped register reset driver
+
+This is a generic reset driver using syscon to map the reset register.
+The reset is generally performed with a write to the reset register
+defined by the register map pointed by syscon reference plus the offset
+with the mask defined in the reboot node.
+
+Required properties:
+- compatible: should contain "syscon-reboot"
+- regmap: this is phandle to the register map node
+- offset: offset in the register map for the reboot register (in bytes)
+- mask: the reset value written to the reboot register (32 bit access)
+
+Default will be little endian mode, 32 bit access only.
+
+Examples:
+
+	reboot {
+	   compatible = "syscon-reboot";
+	   regmap = <&regmapnode>;
+	   offset = <0x0>;
+	   mask = <0x1>;
+	};

+APM X-GENE SoC series SCU Registers

+This system clock unit contain various register that control block resets,

+
+Properties:
+ - compatible : should contain two values. First value must be:

+
+ - reg : offset and length of the register set.
