[PATCH RFC 3/7] dt-bindings: interrupt-controller: thead,c900-aclint-sswi: Add SpacemiT K3

[Junhui Liu]

Add support for the ACLINT SSWI found in the SpacemiT K3 SoC. The
hardware provides a ACLINT SSWI unit. Adding riscv,aclint-sswi as a
fallback compatible allows direct reuse of the SSWI driver when
introducing new compatible strings in the future.
