Convert CS4236B driver - 2.5.44 (3/4)

PATCH 1/1 Convert CS4236B driver - 2.5.44 (3/4)
This patch converts the CS4236B sound card driver to the new PnP APIs. Also it makes pnp_driver_register return the number of matches during the driver add. This should serve as a sample driver, along with the serial and parport_pc.
Applies against 2.5.44.
Thanks,
Adam
