LINT64: Document the kernel options of the sound stack.

Also, comment out SND_DIAGNOSTIC which is currently broken.

+# Following options are intended for debugging/testing purposes:
+#
+# SND_DEBUG                    Enable extra debugging code that includes
+#                              sanity checking and possible increase of
+#                              verbosity.
+#
+# SND_DIAGNOSTIC               Similar in a spirit of INVARIANTS/DIAGNOSTIC,
+#                              zero tolerance against inconsistencies.
+#
+# SND_FEEDER_MULTIFORMAT       By default, only 16/32 bit feeders are compiled
+#                              in. This options enable most feeder converters
+#                              except for 8bit. WARNING: May bloat the kernel.
+#
+# SND_FEEDER_FULL_MULTIFORMAT  Ditto, but includes 8bit feeders as well.
+#
+# SND_FEEDER_RATE_HP           (feeder_rate) High precision 64bit arithmetic
+#                              as much as possible (the default trying to
+#                              avoid it). Possible slowdown.
+#
+# SND_PCM_64                   (Only applicable for i386/32bit arch)
+#                              Process 32bit samples through 64bit
+#                              integer/arithmetic. Slight increase of dynamic
+#                              range at a cost of possible slowdown.
+#
+# SND_OLDSTEREO                Only 2 channels are allowed, effectively
+#                              disabling multichannel processing.
