dt-bindings: ipmi: Convert IPMI-SMIC bindings to json-schema
Convert the generic IPMI controller bindings to DT schema format using json-schema. The device_type property is deprecated for most node per the DT spec, but at least the Linux driver matches on it, so I keep it in. The Linux driver parses for some additional and optional properties, but there are no in-tree users. Let's allow extra properties to cover any other users.

-IPMI device
-
-Required properties:
-- compatible: should be one of ipmi-kcs, ipmi-smic, or ipmi-bt
-- device_type: should be ipmi
-- reg: Address and length of the register set for the device
-
-Optional properties:
-- interrupts: The interrupt for the device. Without this the interface
- is polled.
-- reg-size - The size of the register. Defaults to 1
-- reg-spacing - The number of bytes between register starts. Defaults to 1
-- reg-shift - The amount to shift the registers to the right to get the data
- into bit zero.
-
-Example:
-
-smic@fff3a000 {
- compatible = "ipmi-smic";
- device_type = "ipmi";
- reg = <0xfff3a000 0x1000>;
- interrupts = <0 24 4>;
- reg-size = <4>;
- reg-spacing = <4>;
-};
