[PATCH] arm/fvpboot: Disable timing annotation by default

[Peter Hoyes]

From: Peter Hoyes <Peter.Hoyes@arm.com>

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.
