[meta-freescale] [Documentation][PATCH 01/14] scripts/output-machine-list: add commands interface

[Mario Domenech Goulart]

Now output-machine-list accepts two commands: one to list machine
names (list) and another one to print a formatted table of machines
and their corresponding attributes (tabularize).

The script output is now printed to the standard output.
