omap: rx51: Don't power up speaker amplifier at bootup
Speaker amplifier is accidentally powered up in early TWL gpio setup. This causes a few mA of needless battery current consumption. Without this patch the amplifier can be shutdown only by having one active audio playback and shutdown cycle to speaker output. Thanks to Kalle Jokiniemi <kalle.jokiniemi@nokia.com> for noticing the issue.
