[PATCH 2/2] bootm: fix printing kernel command line

[Sascha Hauer <s.hauer@pengutronix.de>]

Since af084cae41ce ("of: never fixup internal live tree")
of_get_fixed_tree() no longer fixes the tree passed into the function, but a copy thereof
instead. in bootm this has the side effect that data->of_root_node
will no longer contain a fixed tree, but the original tree instead.
data->of_root_node is used later for printing the kernel command line
and it's also printed with bootm -vv, so this pointer should really
hold a fixed tree.
Fix this by not using of_get_fixed_tree() but open coding it.
