MIPS: Use ram_top, not bi_memsize, in arch_lmb_reserve
When calculating the region to reserve for the stack in arch_lmb_reserve, make use of ram_top instead of adding bi_memsize to CONFIG_SYS_SDRAM_BASE. This avoids overflow if the system has enough memory to reach the end of the address space. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
