timestamps: Add timestamps around the vbios load & init
Add timestamps before and after the vBIOS load and after the vBIOS
run. This lets us see exactly how long it took to load it from the
ROM chip, and how long it takes to run.
BUG=b:64549506
TEST=Build & boot Grunt, see vBIOS load & initialization times.
