arm/fvpboot: Disable timing annotation by default

Browse Source 
Timing Annotation is a feature of the model that enables high-level
performance estimations to be made [1]. It is not needed to demonstrate
a functioning software stack so set FASTSIM_DISABLE_TA to 1 in the model
environment to disable this feature. This also improves model
performance.
