There is no need to check for CONFIG_E500 anywhere in
arch/powerpc/cpu/mpc85xx.  mpc85xx implies CONFIG_E500.

I don't see anywhere in this patchset where you set
CONFIG_SYS_PPC_E500_DEBUG_TLB on any actual board.  It should be set for
all e500v1/v2, not just so that debug works but so that this code
remains tested.
