Some of the RPMI service groups may need additional context and
special handling when transferring messages via underlying mailbox
channel so introduce optional MPXY RPMI service group operations
for this purpose.

Instead of having one common FDT MPXY RPMI mailbox client drivers
for various RPMI service groups, split this driver into two parts:
1) Common MPXY RPMI mailbox client library
2) MPXY driver for RPMI clock service group
The above split enables having a separate MPXY driver for each
RPMI clock service group and #1 (above) will allow code sharing
between various MPXY RPMI drivers.

The generic platform can have multiple MPXY drivers so add a simple
FDT based MPXY driver framework.
