Modified Files:
	src/sys/arch/hpcmips/vr: vraiu.c

Log Message:
The vraiu(4) hardware doesn't provide any interface for volume control.
Added software volume control functionality in vraiu_volume(), called from
vraiu_start(). Can be changed by the mixerctl 'inputs.dac' -- 0 is muted,
255 is the level that the driver previously outputted (quite loud on the
IBM Workpad Z50), and everything else is a smooth transition between the
two. Thanks to toddpw@ for lending me the hardware to test these changes.
