In case the image that is wrapped in the nxp_imx8mcst already contains
an FCFB header which is mandatory for SPI NOR boot, then the IVT is at
offset 0x1000 instead of offset 0x0, but the whole image including the
FCFB header must be signed to prevent attacker from tampering with any
of the headers. Add the FCFB handling.
