mailbox: sun6i-msgbox: Add a new mailbox driver
Allwinner sun6i, sun8i, sun9i, and sun50i SoCs contain a hardware message box used for communication between the ARM CPUs and the ARISC management coprocessor. This mailbox contains 8 unidirectional 4-message FIFOs. Add a driver for it, so it can be used with the Linux mailbox framework.
