drivers: fastboot: zImage flashing is not supported for v3, v4
With vendor boot image introduced in version 3 and 4 of boot
image header, boot information is located in both boot image
and vendor boot image.
Flashing zImage is not supported for version 3 and 4 since this
requires updating vendor boot image and/or generating a new image.
Print an error message when the boot image header version is
greater than 2.
