This patch series allows users to access SCMI base protocol provided by
SCMI server (platform). It will also be utilized in separate patches
in the future to add sanity/validity checks for other protocols.
See SCMI specification document v3.2 beta[1] for more details about SCMI
base protocol.

What is currently not implemented is
- SCMI_BASE_NOTIFY_ERRORS command and notification callback mechanism

This feature won't be very useful in the current U-Boot environment.
