[PATCH 3/7] blspec: don't clobber bootm.image on boot attempt

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

bootm_data_init_defaults() initialized the defaults from global
variables and thus the blspec code cleared the global variables.

This roundabout way can be confusing to users as a failing bootloader
spec boot would clobber these variables.

Let's improve upon this by just ignoring the variables explicitly
instead of clobbering them.
