Remove references to old project name from common files

The project has been renamed from "Arm Trusted Firmware (ATF)" to
"Trusted Firmware-A (TF-A)" long ago. A few references to the old
project name that still remained in various places have now been
removed.

This change doesn't affect any platform files. Any "ATF" references
inside platform files, still remain.

 We suspect the time for lead CPU 4 is shorter than CPU 5 due to subtle cache
 effects, given that these measurements are at the nano-second level.
