[PATCH] pmac: Improve sleep code of tumbler driver

This patch improves the behaviour of the "tumbler/snapper" driver used on
newer PowerMacs during sleep.  It properly set the HW mutes to shut down
amplifiers and does an analog shutdown of the codec.  That might improve
power consumption during sleep on a number of machines.
