Populate FVP YAML files for cortex-a73x4 and cortex-a73x4-a53x4 models

FVP YAML file generation is a two step process: 1. yaml template
creation and 2. fvp values replacement on template created by 1. This
patch only relates to 2 and specifically for 'cortex-a73x4' and
'cortex-a73x4-a53x4' models.
