On some platforms, root port has neither MSI/MSI-X nor INTx interrupt
generated in RC mode. In this case, we have to use other interrupt(e.g.
system shared interrupt) for port service irq to have AER, Hot-plug, etc,
services to work.

acpi_memory_device_remove() has been prepared to remove physical memory.
But, the function only frees acpi_memory_device currentlry.
The patch adds following functions into acpi_memory_device_remove():
- offline memory
- remove physical memory. It only check whether memory is online or not.
If system supports memory hot-remove, online_pages() may online removed pages.
So online_pages() need to check whether onlining pages are present or not.

All pages of virtual mapping in removed memory cannot be freed, since some pages
