In SCMI base protocol version 2 (0x20000), new interfaces,
BASE_SET_DEVICE_PERMISSIONS/BASE_SET_PROTOCOL_PERMISSIONS/
BASE_RESET_AGENT_CONFIGURATION, were added. Moreover, the api of
BASE_DISCOVER_AGENT was changed to support self-agent discovery.
So the driver expects SCMI firmware support version 2 of base protocol.

SCMI base protocol is mandatory according to the SCMI specification.
With this patch, SCMI base protocol can be accessed via SCMI transport
layers. All the commands, except SCMI_BASE_NOTIFY_ERRORS, are supported.
This is because U-Boot doesn't support interrupts and the current transport
layers are not able to handle asynchronous messages properly.
