dt-bindings: interrupt-controller: Convert ti,keystone-irq to DT schema

Convert the TI Keystone 2 interrupt controller binding to schema format.
It's a straight-forward conversion of the typical interrupt controller.

-Keystone 2 IRQ controller IP
-
-On Keystone SOCs, DSP cores can send interrupts to ARM
-host using the IRQ controller IP. It provides 28 IRQ signals to ARM.
-The IRQ handler running on HOST OS can identify DSP signal source by
-analyzing SRCCx bits in IPCARx registers. This is one of the component
-used by the IPC mechanism used on Keystone SOCs.
-
-Required Properties:
-- compatible: should be "ti,keystone-irq"
-- ti,syscon-dev : phandle and offset pair. The phandle to syscon used to
-                       access device control registers and the offset inside
-                       device control registers range.
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode interrupt
-                                        source should be 1.
-- interrupts: interrupt reference to primary interrupt controller
