Subject: [PATCH v2 09/14] dt-bindings: interrupt-controller: Convert Broadcom STB L2 to YAML

Convert the Broadcom STB L2 generic Level 2 interrupt controller Device
Tree binding to YAML to help with validation.

-Broadcom Generic Level 2 Interrupt Controller
-
-Required properties:
-
-- compatible: should be one of:
-	      "brcm,hif-spi-l2-intc" or
-	      "brcm,upg-aux-aon-l2-intc" or
-	      "brcm,l2-intc" for latched interrupt controllers
-              should be "brcm,bcm7271-l2-intc" for level interrupt controllers
-- reg: specifies the base physical address and size of the registers
-- interrupt-controller: identifies the node as an interrupt controller
-- #interrupt-cells: specifies the number of cells needed to encode an
-  interrupt source. Should be 1.
-- interrupts: specifies the interrupt line in the interrupt-parent irq space
-  to be used for cascading
-
-Optional properties:
-
-- brcm,irq-can-wake: If present, this means the L2 controller can be used as a
-  wakeup source for system suspend/resume.
-
-Example:
-
-hif_intr2_intc: interrupt-controller@...41000 {
-	compatible = "brcm,l2-intc";
-	reg = <0xf0441000 0x30>;
-	interrupt-controller;
-	#interrupt-cells = <1>;
-	interrupt-parent = <&intc>;
-	interrupts = <0x0 0x20 0x0>;
-};
