ALSA: hda/conexant: Add pin config quirk for Huawei Matebook

Browse source

The headphone jack is not detected on this Huawei Matebook (Conexant
SN6140 codec). The BIOS incorrectly marks Pin 0x18 as [N/A], causing
the driver to report hp_outs=0 and no "Headphones" output appears.

Override the pin configuration for NID 0x18 to set it as a headphone
jack, which restores proper detection and audio routing.
