MLK-20467 imx8m: Fix issue for booting signed image through uuu

The SPL loads the FIT image FDT part to an address related with the device
block length. This length is 512 for SD/MMC and is 1 for other devices
like SDP, NOR, NAND, SPI, etc.
When signing FIT image, we use fixed address caculated by SD/MMC block length
to sign FDT part. Thus, when booting through uuu, this causes mismatch and
gets authentication failed.

Fix the issue by providing a override function for this FIT buffer address.
When secure boot is enabled, adjust the addresses of other devices to be same
with SD/MMC.
