[PATCH 3/4] amend! bootm: add fitimage command line to bootargs

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

From: Ahmad Fatoum <a.fatoum@barebox.org>

bootm: add fitimage command line to bootargs

Since FIT image specification v0.9, it is now possible to pass command
line arguments for the next boot stage in FIT images.

Add parsing of the cmdline optional property when reading the fitimage.
Create a new bootm-scope global variable that will be appended to the
command line when CONFIG_FLEXIBLE_BOOTARGS is enabled.
