Add support for printing version at runtime
Print out Trusted Firmware version at runtime at each BL stage.
Message consists of TF version as defined statically in the Makefile
(e.g. v0.4), build mode (debug|release) and a customizable build
string:
1. By defining BUILD_STRING in command line when building TF
2. Default string is git commit ID
3. Empty if git meta-data is not available
Fixes ARM-software/tf-issues#203
