feat(fvp): add SoC name support to FVP

This patch adds support in the FVP platform for the SoC name
field in SMCCC_ARCH_SOC_ID. The returned string is formatted as:

  "Arm Platform Revision <SoC Revision>"

This adheres to the guideline that the SoC name must not expose
information beyond what is already captured in <SoC Version, SoC
Revision>.
