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.

Changes in v2:
Make the BOOT_FROM field mandatory, i.e. exit with an error message if there is no valid flash_offset set. Do the same handling in header v1 and v2, not only in v2.
Note: This is tested only for header v2.
