x86, numa, acpi, memory-hotplug: make movable_node have higher priority

If users specify the original movablecore=nn@ss boot option, the kernel
will arrange [ss, ss+nn) as ZONE_MOVABLE.  The kernelcore=nn@ss boot
option is similar except it specifies ZONE_NORMAL ranges.

Now, if users specify "movable_node" in kernel commandline, the kernel
will arrange hotpluggable memory in SRAT as ZONE_MOVABLE.  And if users
do this, all the other movablecore=nn@ss and kernelcore=nn@ss options
should be ignored.

For those who don't want this, just specify nothing.  The kernel will
act as before.
