gusclassic: port to isa_bus infrastructure

snd_gusclassic_init() is no more -- the flags are already initialized to 
0 as part of the snd_gus_card structure itself and while I sort of 
expect that the C standard won't have many positive things to say about 
initializing bitfields through a kzalloc(), the code relies on this for 
other flags as well. The joystick_dac value is set directly in probe() 
now (I saw it's the same in all gus variants so should probably at some 
point be moved to snd_gus_create).

This has been tested, and works the same as before, which is to say not 
quite right.

It plays okay through ALSA's OSS emulation, but native ALSA complains:

   ALSA lib pcm.c:2017:(snd_pcm_open_conf) Invalid type for PCM
   default definition (id: default, value: cards.pcm.default)
   ALSA snd_pcm_open error: Invalid argument

Using "hw:0" gets:

   ALSA snd_pcm_hw_params_set_access error: Invalid argument

and "plughw:0" gets:

   ALSA lib pcm_plug.c:773:(snd_pcm_plug_hw_refine_schange) Unable to
   find an usable access for 'plughw:0'
   ALSA snd_pcm_hw_params_set_access error: Invalid argument

Although I'm familiar with the ALSA kernel side, I can't say the same 
about the userland or the interaction between the two and this looks 
like it might be a problem at that level. So I thought I'd just ask 
you... ;-)

(but as said, patch is good to go)

Rene.
