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 Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
