[ Upstream commit83f672a7f6] When MACH_IS_MVME147, the boot console calls mvme147_scc_write() to generate console output. That will continue to work even after debug_cons_nputs() becomes unavailable so there's no need to unregister the boot console. Take the opportunity to remove a repeated MACH_IS_* test. Use the actual .write method (instead of a wrapper) and test that pointer instead. This means adding an unused parameter to debug_cons_nputs() for consistency with the struct console API. early_printk.c is only built when CONFIG_EARLY_PRINTK=y. As of late, head.S is only built when CONFIG_MMU_MOTOROLA=y. So let the former symbol depend on the latter, to obviate some ifdef conditionals.
