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 Change-Id: I9d08c2dfd349022808fcc884724f677eefdc1452
