The JZ4780 I2S can feed either the internal audio codec or the HDMI
transmitter, but not both at the same time. This patch:

 - Adds a dev.pcm.0.internal_codec sysctl node for selecting between
   internal and external codec
 - Changes playback sample rate from 96 kHz to 48 kHz for HDMI compatibility
 - Enables i2s clock on codec access
