[flashrom] [PATCH] Split off CLI functions from flashrom.c

[Carl-Daniel Hailfinger]

This was long overdue.

Move the CLI related functions main() and cli_usage() to cli_classic.c
and rename them accordingly. For now, main() just calls cli_classic(),
but alternative frontends can be switched in main().
Annotate remaining help texts with CLI dependency inside flashrom.c with
a FIXME comment.

Now people can go and create different frontends and be happy. Please
note that any other frontend will have to sort of duplicate the probing
code in cli_classic.c. Refactoring that part of the code is possible,
but not easy because we still want to print instructive help messages
for users.
