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.
