    ALSA: hda - Enable beep on Realtek codecs with PCI SSID override
    
    When the PCI SSID gives an overriding SKU assno, PC-beep bit isn't
    detected (since it's located over 16bit), resulting in no PC beep.
    Also, many devices seem ignoring the requirement by Realtek's spec
    for SSID numbers, and it also confuses the PC beep detection.
    
    This patch assumes the PC beep is available on every machine with
    PCI SSID override.  It's a regression fix from 2.6.34.
