The supervisor software can directly receive most of the system MSIs
except P2A doorbell and MSIs preferred to be handled in M-mode.
Add MPXY RPMI mailbox client driver for the System MSI service group.

lib: utils: Populate MPXY channel attributes from RPMI channel attributes2025-02-13T05:40:03+00:00Anup Patelapatel@ventanamicro.com2025-01-12T11:29:46+00:00urn:sha1:e4bc55930b1755f7ec045ba2ad158868e7f6dd5d
Use the RPMI mailbox channel attributes to populate MPXY channel
attributes instead of hard coding them.

The local variable declarations should be at the start of function
and preferrably organized like a inverted pyramid.

lib: utils: Drop notifications from MPXY RPMI mailbox client2025-02-13T05:40:03+00:00Anup Patelapatel@ventanamicro.com2025-01-12T05:10:01+00:00urn:sha1:879ee6859cfb2d3241923af615f7f1e77aba32c5
Currently, the common MPXY RPMI mailbox client does not support
notifications so no need for dummy notifications support.

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.

The mpxy_rpmi_mbox_data is provided by RPMI service group specific
MPXY driver to the common MPXY RPMI mailbox client implementation
so let's constantify mpxy_rpmi_mbox_data in mpxy_rpmi_mbox so that
it is not accidently modified.

lib: utils: Split the FDT MPXY RPMI mailbox client into two parts2025-02-13T05:40:03+00:00Anup Patelapatel@ventanamicro.com2025-01-11T09:08:34+00:00urn:sha1:d14340cb315195bd556ed89d5ca7a49335768ddc
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.

lib: utils: Mark RPMI drivers as experimental2024-12-21T12:52:47+00:00Samuel Hollandsamuel.holland@sifive.com2024-12-19T05:02:39+00:00urn:sha1:8d8cc9507bd79afbe5c29b5d82868269691152f9
These drivers were merged on an experimental basis without the RPMI
specification being frozen. As a result, they may not be compatible with
the frozen version of the RPMI protocol. Additionally, their devicetree
bindings have not been reviewed and are subject to change. Warn the user
that these drivers make no compatibility guarantees, and that their
behavior and devicetree bindings may change incompatibly in future
versions of OpenSBI.

Add a generic RPMI mailbox client driver which provides a MPXY channel.
Initially, this driver only supports RPMI clock service group but can
be extended to support multiple RPMI service groups.
