The ida_simple_remove should probably be part of the class release
function to make everything work right

It looks to me bus instead of class is the correct abstraction here since
the devices share a set of programming interface but not the semantics.

device_release() doesn't call the bus release? You have dev, type or
class to choose from. Type is rarely used and doesn't seem to be used
by vdpa, so class seems the right choice
