Revert "[new uImage] Add autostart flag to bootm_headers structure"

Browse Source 
This reverts commit f5614e7926863bf0225ec860d9b319741a9c4004.

The commit was based on a misunderstanding of the (documented)
meaning of the 'autostart' environment variable. It might cause
boards to hang if 'autostart' was used, with the potential to brick
them. Go back to the documented behaviour.

Conflicts:

	common/cmd_bootm.c
	common/image.c
	include/image.h
