powerpc/mpc85xx: Use GOT when loading IVORs post-relocation
Commit 96d2bb952bb ("powerpc/mpc85xx: Don't relocate exception vectors") simplified IVOR initialization a bit too much, failing to use the post-relocation offset. This doesn't cause a problem with normal NOR boot, in which both the pre-relocation and post-relocation addresses are 64 KiB aligned. However, if TEXT_BASE is only 4 KiB aligned, such as for NAND/SD/etc. boot on some targets, as well as the QEMU target, the post-relocation address will not be the same in the lower 16 bits, as reserve_uboot() ensures that the relocation address is always 64 KiB aligned even if the pre-relocation address was not. Use the GOT to get the proper post-relocation offsets.
