fix(scmi): induce a delay in monitoring SCMI channel status

Reading the SCMI mailbox status in polling mode causes a burst of bus
accesses. On certain platforms, this would not be ideal as the shared
bus on the CPU subsystem might cause contentions across all the CPUs.
So allow platforms to specify a delay to be introduced while polling.

fix(scmi): relax requirement for exact protocol version

Currently, for the supported SCMI protocols, the version returned by the SCMI
platform agent must be exactly matching the driver's version (major version).

The recent change for the required version of Power Domain protocol means that
the platform must return version 2.0. This can be however a limitation in some
cases, where a SCMI-v1.0 platform can still be considered compatible with the
driver supported in firmware.

Relax the protocol version requirement such that any version older than the
one supported by the drivers can still be compatible.

Note: For now this has effect only on Power Domain protocol, as the other
drivers still require the "base" version 1.0.

drivers/arm/scmi: allow use of multiple SCMI channels

On systems that have multiple platform components that can interpret the
SCMI messages, there is a need to support multiple SCMI channels (one
each to those platform components). Extend the existing SCMI interface
that currently supports only a single SCMI channel to support multiple
SCMI channels.

Improved support for W=1 compilation flag by solving missing-prototypes
and old-style-definition warnings.

The libraries are compiling with warnings (which turn into errors with
the Werror flag).

Outside of libraries, some warnings cannot be fixed without heavy
structural changes.
