cmd_bootm.c: Make bootz handle BOOTM_STATE_FINDOTHER itself
As a zImage does not have a U-Boot header, we cannot really do what BOOTM_STATE_FINDOTHER does, exactly. Break the ramdisk/fdt portions of bootm_find_other into bootm_find_ramdisk/fdt which can be called in both cases. Signed-off-by: Tom Rini <trini@ti.com>
