ci: use FVP_Base_RevC-2xAEMvA for aemva models

Currently base-aemv8a uses FVP_Base_RevC-2xAEMvA model, which is the
default choice whereas base-aemva is using FVP_Base_AEMvA model. To make
the a common naming let base-aemva also use the default model.

So after this patch both base-aemv8a and base-aemva are exactly same
which will be changed in a future patch to use only base-aemva
everywhere.
