mknod: widen the parameters to match kernel
ustat: same, + remove superfluous "conversion" which does nothing at best, loses high dev bits at worst i386/bits/kernel_stat.h: update to reflect reality (wider dev_t) h8300/bits/kernel_stat.h: same arm/bits/kernel_stat.h: cosmetics to match kernel header to the letter
