Freescale's e500v1 and e500v2 cores (used in mpc85xx chips) have some
restrictions on external debugging (JTAG). Need to define define 
CONFIG_SYS_PPC_E500_DEBUG_TLB to enable a temporary TLB entry to be
used during boot to work around the limitations.

Enable missed e500v2 SoC i.e. MPC8536, MPC8544, MPC8548 and MPC8572 for 
debug support.
