Add IORESOUCE_BUSY flag for System RAM
i386 and x86-64 registers System RAM as IORESOURCE_MEM | IORESOURCE_BUSY.
But ia64 registers it as IORESOURCE_MEM only.
In addition, memory hotplug code registers new memory as IORESOURCE_MEM too.
This difference causes a failure of memory unplug of x86-64. This patch
fixes it.
This patch adds IORESOURCE_BUSY to avoid potential overlap mapping by PCI
device.
