[ALSA] switching rate in STAC9460 codec of Prodigy192

* support for switching rate in STAC9460 - using set_rate_val of the akm
infrastructure
* listing all STAC9460 registers in proc
* disabling mpu401 device for Prodigy192 - otherwise the currently
  flawed mpu401 code hangs kernel when opening the midi device
* removing old unused commented-out code
