13.12: use FVP models

Tidy up references to RTSM.

FVP models are now available to Linaro, so we have tested the 13.12
release using FVP rather then the older RTSM models.

DS-5 now also includes an FVP model for A9, so we also use that rather
than the older RTSM models.

that will be completely re-written in a subsequent patch.
