[Rohan Mithari]

Convert the legacy pvpanic-mmio txt binding into YAML schema
format for device tree validation support.

---
Changes in v2:
- Remove legacy txt binding
- Fix reg example format
- Add trailing newline
- Run checkpatch validation with --no-tree

-* QEMU PVPANIC MMIO Configuration bindings
-
-QEMU's emulation / virtualization targets provide the following PVPANIC
-MMIO Configuration interface on the "virt" machine.
-type:
-
-- a read-write, 16-bit wide data register.
-
-QEMU exposes the data register to guests as memory mapped registers.
-
-Required properties:
-
-- compatible: "qemu,pvpanic-mmio".
-- reg: the MMIO region used by the device.
-  * Bytes 0x0  Write panic event to the reg when guest OS panics.
-  * Bytes 0x1  Reserved.
-
-Example:
-
-/ {
-        #size-cells = <0x2>;
-        #address-cells = <0x2>;
-
-        pvpanic-mmio@9060000 {
-                compatible = "qemu,pvpanic-mmio";
-                reg = <0x0 0x9060000 0x0 0x2>;
-        };
-};
