[PATCH v2] mx8m: csf.sh: pad csf blob for u-boot.itb to CSF_SIZE minus IVT header

[sbabic@denx.de]

> When built with CONFIG_IMX_HAB, the full FIT image, including stuff
> tacked on beyond the end of the fdt structure, is expected to be (fdt
> size rounded up to 0x1000 boundary)+CONFIG_CSF_SIZE.
> Now, when the FIT image is loaded from a storage device, it doesn't
> really matter that the flash.bin that gets written to target isn't
> quite that big - we will just load some garbage bytes that are never
> read or used for anything. But when flash.bin is uploaded via uuu,
> it's important that we actually serve at least as many bytes as the
> target expects, or we will hang in rom_api_download_image().
> Extend the logic in the csf.sh script so that the csf blob is padded
> to CONFIG_CSF_SIZE minus the size of the IVT header.
