ACPI: save device_type in acpi_device
Most uses of the ACPI bus device_type (ACPI_BUS_TYPE_DEVICE,
ACPI_BUS_TYPE_POWER, etc) are during device initialization, but
we do need it later for notify handler installation, since that
is different for fixed hardware devices vs. namespace devices.
This patch saves the device_type in the acpi_device structure,
so we can check that rather than comparing against the _HID string.
