This fixed a problem with lockdep touching per-cpu areas very early in boot. However if we combine CONFIG_LOCK_STAT=y with any of the PPC_EARLY_DEBUG options, we can hit the same problem in udbg_early_init(). To avoid that we need to set the data_offset of the boot_paca also. So factor out the fixup logic and call it for both the boot_paca, and "the paca of the boot cpu".
