firmware: arm_scmi: Remove const from transport descriptors

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.
