[PATCH v2] docs: iio: backend: use literal block for commands

[Randy Dunlap <rdunlap@infradead.org>]

Use literal blocks for 'cat' and 'echo' commands to separate them from
the surrounding text. Otherwise the lines run together, without any
clear break before or after the commands.

Use shell comment style to go along with the shell commands.
