ACPI: bus: Drop two fields from struct acpi_device_pnp

Browse source

There are two fields in struct acpi_device_pnp, device_name and
device_class, that were supposed to be populated and used by device
drivers, but they have never been used consistently and now they
are only set for the bus object in acpi_set_pnp_ids() (and never
read afterward).

Drop them along with all of the associated symbols except for
MAX_ACPI_CLASS_NAME_LEN and the acpi_device_class typedef that
are used by the ACPI netlink messaging code.  Move those two
definitions closer to the struct acpi_bus_event that refers to
the acpi_device_class type.

No intentional functional impact.
