powerpc/mpc85xx:Add debugger support for e500v2 SoC
Freescale's e500v1 and e500v2 cores (used in mpc85xx chips) have some
restrictions on external debugging (JTAG).
So define CONFIG_SYS_PPC_E500_DEBUG_TLB to enable a temporary TLB entry to be
used during boot to work around the limitations.
Please refer doc/README.mpc85xx for more information
