m68k: /proc/hardware should depend on PROC_FS

When CONFIG_PROC_FS is not set, there is a build error for an unused
function. Make PROC_HARDWARE depend on PROC_FS to prevent this error.

../arch/m68k/kernel/setup_mm.c:477:12: error: 'hardware_proc_show' defined but not used [-Werror=unused-function]
