[PATCH] powerpc/prom_init: Undo relocation before entering secure mode

The ultravisor will do an integrity check of the kernel image but we relocated it so the check will fail. Restore the original image by relocating it back to the kernel virtual base address. This works because during build vmlinux is linked with an expected virtual runtime address of KERNELBASE.
