[PATCH 09/16] bootm: stash initial OS address/entry in image_data

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

Save the initial os_address and os_entry values that were passed to
bootm_boot() in new os_address_hint and os_entry_hint fields. These
preserve the originally requested values even if os_address/os_entry
are modified during the boot process.
