tools: kwbimage/kwboot: Check ext field for non-zero value
Despite the official specification, BootROM does not look at the lowest bit
of ext field but rather checks if ext field is non-zero.
Moreover original Marvell doimage tool puts into the mhdr->ext field the
number of extended headers, so basically it sets ext filed to non-zero
value if some extended header is present.
Fix U-Boot dumpimage and kwboot tools to parse correctly also kwbimage
files created by Marvell doimage tool, in the same way as the BootROM is
doing it when booting these images.
