Currently, we get 256MB as the default, but since all the 86xx
board configs define a 2G BAT mapping for RAM, raise default
to 2G.

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

CONFIG_SDRAM_PPC4xx_IBM_DDR2 is not set when include/asm-ppc/config.h is
included. So for katmai, CONFIG_MAX_MEM_MAPPED will get set to 256MB.
It makes perfect sense to set CONFIG_MAX_MEM_MAPPED to 2GB for all PPC4xx
boards right now.

Moved CONFIG_MAX_MEM_MAPPED to the asm/config.h so its kept consistent
between the two current users (lib_ppc/board.c, 44x SPD DDR2).

We have common defines that we duplicate in various ways. Having an
arch specific config.h gives us a common location for those defines.
Eventually we should be able to replace this when we have proper
Kconfig support.
