[PATCH 4/5] Documentation: gen_commands.py: use literal block for help text

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The help text can have lists, like in the boot command[1] and printing
this as normal text messes up the formatting.
Therefore, let's just print it as a code block.

This doesn't solve interleaved output like fiptool's, but it makes e.g.
the boot help text or menu actually readable.
