ALSA: seq: Use bus specific probe and remove
Introduce a bus specific probe and remove function. For now this only
allows to get rid of a cast of the generic device to an snd_seq device
in the drivers and changes the remove prototype to return void---a
non-zero return value is ignored anyhow.
The objective is to get rid of users of struct device callbacks
.probe(), .remove() and .shutdown() to eventually remove these. Until
all snd_seq drivers are converted this results in a runtime warning
about the drivers needing an update because there is a bus probe
function and a driver probe function.
