powerpc/mpc85xx: Add clear_ddr_tlbs function
This is useful when we just want to wipe out the TLBs. There's currently a function that resets the ddr tlbs to a different value; it is changed to utilize this function. The new function can be used in conjunction with setup_ddr_tlbs() for a board to temporarily map/unmap the DDR address range as needed.
