sound: remove OSS Ensoniq SoundScape driver 

The OSS driver for Ensoniq SoundScape cards is broken after conversion
to mutexes and a new ALSA snd-sscape driver handles all devices handled
by the OSS one.

The ALSA driver was tested with these cards:
Spea V7 MediaFX
Ensoniq Soundscape Elite
Ensoniq Soundscape VIVO (this card is not handled by the OSS driver)

Answer Y if you have a sound card based on the Ensoniq SoundScape
chipset. Such cards are being manufactured at least by Ensoniq, Spea
and Reveal (Reveal makes also other cards).
If you compile the driver into the kernel, you have to add
"sscape=<io>,<irq>,<dma>,<mpuio>,<mpuirq>" to the kernel command
line.
