[S390] Fix IPL from NSS.
IPL from NSS didn't work because the memory detection routine omits any memory sections with a size lower than what MAX_ORDER defines. This causes the detection routine to skip the first memory segment which has a size of 1MB. Which later on will let the kernel think that there is no memory available at all. Since in addition the z/VM memory increment size is 1MB force MAX_ORDER to be 9, so we can support 1MB segments.
