While "flash bank" syntax has been changed long ago,
several tcl script are still not fully update.

Fix following cases related with "cfi" driver:
- syntax error: the mandatory <name> parameter is missing
- warning: the <target> parameter is a number, instead of
  the target name
- the comment line above the command does not report
  actual syntax

Sets $_FLASHNAME to "$_CHIPNAME.flash" and passes it as the
first argument to 'flash bank'.

This is the very basic board config for the balloon3 board cpu JTAG
channel.

The rest of the config comprises another 14 .cfg files which I suspect
openocd doesn't really want all of. I'm still not sure how to deal
with this. I'll post another mail/patch to discuss.
