Nishanth Aravamudan 989a0b248b [ALSA] Fix-up sleeping in sound/ppc 
PPC AWACS driver,PPC PMAC driver,PPC Tumbler driver
Description: Fix-up sleeping in sound/ppc. Replace big_mdelay() with
msleep() to guarantee the task delays as expected. This also involved
replacing/removing custom sleep functions.
