f8523cb081 85xx: Fix how we map DDR memory
Previously we only allowed power-of-two memory sizes and didnt
handle >2G of memory.  Now we will map up to CONFIG_MAX_MEM_MAPPED
and should properly handle any size that we can make in the TLBs
we have available to us

950264317e Change DDR tlb start entry to CONFIG param for 85xx
So that we can locate the DDR tlb start entry to the value other than 8. By
default, it is still 8.
