feat(fvp): capture timestamps in bl stages
When ENABLE_RUNTIME_INSTRUMENTATION flag is set timestamps are captured
and output to the fvp console at various boot stages using the PMF
library (which are based on aarch timers).
Timestamps are captured at entry and exit points for Bl1, Bl2
and, Bl3 respectively.
