lib/utils: Add RPMI messaging protocol and shared memory transport support
The RISC-V Platform Management Interface (RPMI) defines a messaging protocol
and shared memory based transport for bi-directional communication with an
on-chip or external microcontroller.
To support RPMI in OpenSBI, add:
1) The RPMI messaging protocol defines and helper macros
2) A FDT mailbox driver for the RPMI shared memory transport
