layerscape: armv8_64b: fix KERNEL_LOADADDR for linux >= 5.8

In kernel versions newer than 5.8 the arm64 TEXT_OFFSET (0x80000) has
been set to 0x0 (and later removed). This will break Uimages with kernel
load addresses that aren't 2MiB aligned any longer. Resulting in the
kernel silently fail to boot. For layerscape armv8_64b targets this
needs to be changed to 0x80000000 (start of RAM).
