cert_create: update help message
The help message printed by the cert_create tool using the command
line option -h (or --help) does not correctly list all the available
command line options.
This patch reworks the print_help() function to print the help
messages in a data driven approach. For each command line option
registered, an optional help message can be specified, which will
be printed by print_help().
Help messages for the TBBR options (certificates, keys and images)
are also provided.
Fix a small bug in the short options string passed to getopt_long:
the ':' was missing in the '-a' option (this option must take an
argument).
Fixes ARM-software/tf-issues#337
