SCMI transports when built as loadable modules should be loaded by the
subsystem they plug into, based on the related subsystem specific aliases.
Add, where missing, the MODULE_DEVICE_TABLE() directives needed to generate
the aliases required to enable autoloading for SCMI transports.

SCMI virtio transport maximum PDU size is currently hardcoded at build
time; this will not play well with the possibile retrieval of a different
size at run-time.
Make the virtio transport derive the maximum PDU size from the max_msg_size
provided by the SCMI core.
No functional change.

The descriptor structure scmi_desc contains a variety of fields related to
the transport functionalities and it is defined by the transport drivers
themselves; such elements, though, serve varied purposes and have different
lifetime.
In particular, while there are some of those elements that provide a
description of transport features that are supposed to be immutable, on
the other side there are present also some other characteristics that are
instead supposed to be configurable on a per-platform base since they
represent configuration features tied to the specific hardware/firmware
system.
The immutable fields are already qualified as const on the their own; get
rid of the structure-level const qualifier which is not needed, so as to
enable possible runtime customization of the mutable configuration
features.
No functional change.

Make SCMI VirtIO transport a standalone driver that can be optionally
loaded as a module.
