ALSA: seq: Define driver object in each driver
This patch moves the driver object initialization and allocation to
each driver's module init/exit code like other normal drivers. The
snd_seq_driver struct is now published in seq_device.h, and each
driver is responsible to define it with proper driver attributes
(name, probe and remove) with snd_seq_driver specific attributes as id
and argsize fields. The helper functions snd_seq_driver_register(),
snd_seq_driver_unregister() and module_snd_seq_driver() are used for
simplifying codes.
