Samuel Holland 25831c44b0 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.
