[PATCH 9/140] ACPI: add acpi_bus_removal_type in acpi_device

From: Li Shaohua <shaohua.li@intel.com>

Add removal_type in structure acpi_device for hot removal.

ACPI_BUS_REMOVAL_EJECT is used for ACPI device hot removal.
Only one parameter is allowed in .remove method due to driver model.
So removal_type is added to indicate different removal type.
