armv8: ls2088aqds: Fix MC firmware loading during SD boot
During SD boot, MC firmware and DPC are copied from SD card to DDR.
Size reserved between MC and DPC firmware on DDR is 1MB.
If the size of MC firmware(load address 0x80000000) is more than 1 MB
then part of MC firmware will be overwritten by DPC firmware (load
address 0x80100000).
Fix: Update the MC/DPL/DPC firmware's DDR address as per their
respective addresses in SD card.
