This change is likely going to break mpc85xx platform because defconfig
files includes all these files which you are going to remove. For
example in arch/powerpc/Makefile is:

PHONY += mpc85xx_smp_defconfig
mpc85xx_smp_defconfig:
	$(call merge_into_defconfig,mpc85xx_base.config,\
		85xx-32bit 85xx-smp 85xx-hw fsl-emb-nonhw)

And for P2020 boards I'm using mpc85xx_smp_defconfig configuration as
this one compiles SMP kernel, ideal for P2020 which is dual-core SoC.
