Pull m68k updates from Geert Uytterhoeven:

 - Revive SCSI and early console support on MVME147

 - Fix early kernel parameters using static keys

 - Prevent and improve handling of kernel configurations that lack
   specific platform, CPU, or MMU support, to avoid build failures

 - Miscellaneous fixes and improvements

 - Defconfig updates
