README declares that CONFIG_SYS_SDRAM_BASE is meant to be the physical
address of SDRAM, but right now that is not the case on MIPS systems. In
preparation for making it so, use phys_to_virt to translate
CONFIG_SYS_SDRAM_BASE to the ram_top field of struct global_data which
is then used to calculate most memory addresses used by U-Boot.
