ALSA: snd-pcsp: add nopcm mode
Currently, if the high-res timers are unavailable, snd-pcsp does not initialize. People who choose it over pcspkr, loose their console beeps in that case and get annoyed. With this patch, the console beeps remain regardless of the high-res timers. Additionally, the "nopcm" modparam is added to forcibly disable the PCM capabilities of the driver.
