imximage: Remove overwriting of flash_offset
The flash header supports different flash offsets for different
boot devices. E.g. parallel NOR or OneNAND use a different offset
than FLASH_OFFSET_STANDARD (== 0x400).
The flash offset is correctly read from the configuration in
parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v1/2().
Fix this by removing this overwriting. Use the flash offset
correctly read from the configuration, instead.
If there is no flash_offset read from the configuration file, i.e.
the BOOT_FROM tag is missing, exit with an error message.
