ALSA: hda - Restore default pin configs for realtek codecs 

Some machines have broken BIOS resume that doesn't restore the default
pin configuration properly, which results in a wrong detection of HP
pin.  This causes a silent speaker output due to missing HP detection.
Related bug: Novell bug#406101
	https://bugzilla.novell.com/show_bug.cgi?id=406101

This patch fixes the issue by saving/restoring the default pin configs
by the driver itself.
