feat(arm): mock support for CCA NV ctr
Arm reference design FVP platforms such as RD-Fremont do not implement
the CCA_FW_NVCOUNTER. Update firmware such that the implementation will
return TRUSTED_FW_NVCOUNTER when the caller requests the CCA NV counter.
This allows the platforms to use the CCA CoT on FVP platforms.
