2018-11-27MLK-20467 imx8m: Fix issue for booting signed image through uuuYe Li
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.

This introduces a problem if the initialization of first controller is failed, for example nothing connect to first controller, then the seq allocated for second controller is 0 not 1.
