driver core: Use attribute groups in struct device_type
Driver core: use attribute groups in struct device_type
Attribute groups are more flexible than attribute lists
(an attribute list can be represented by anonymous group)
so switch struct device_type to use them.
Also rework attribute creation for devices so that they all
cleaned up properly in case of errors.
