ALSA: hda: enable speaker output for Compaq 6530s/6531s
HP Compaq 6530s and 6531s internal speaker is silence or becomes silence
within 1 minute after fresh boot. It is found that pin 0x1c must be set to
PIN_OUT mode to make the speaker work. This is weird - line-in pin 0x1c and
speaker pin 0x16 seem to be unrelated.
The codec differences before/after patch are:
@@ Node 0x17 [Pin Complex] wcaps 0x40020b:
Pin Default 0x41a6e130: [N/A] Mic at Ext Rear
Conn = Digital, Color = White
DefAssociation = 0x3, Sequence = 0x0

- Pin-ctls: 0x24: IN
+ Pin-ctls: 0x40: OUT

+ Pin-ctls: 0x40: OUT VREF_HIZ
Unsolicited: tag=00, enabled=0

0x24
Tests show that it won't impact (external) Mic recording.
