[POWERPC] Remove the unused HTDMSOUND driver

	  Allocate large buffers for MPC8xx Ethernet. Increases throughput

	  and decreases the likelihood of dropped packets, but costs memory.

config HTDMSOUND

	bool "Embedded Planet HIOX Audio"

	depends on SOUND=y

# This doesn't really belong here, but it is convenient to ask

# 8xx specific questions.

 *

 *

 *  Minor numbers for the sound driver.

 *

 *  Unfortunately Creative called the codec chip of SB as a DSP. For this

 *  reason the /dev/dsp is reserved for digitized audio use. There is a

 *  device for true DSP processors but it will be called something else.

 *  In v3.0 it's /dev/sndproc but this could be a temporary solution.
