arm/trusted-services: enable the logging SP

The logging service provides an SPMC agonistic to create log messages.
The current version will simply dump the incoming log messages to a
setial line. Future versions could provide access to log messages from
the NWd, could encrypt the essages and perform more efficient when
logging large messages.

This change enables the logging SP on the fvp_base platform. All log
messages made by SPs after the boot phase will be sent to UART3.
