[PATCH v2] ALSA: hda/conexant: Add pin config quirk for Lenovo IdeaPad Slim 5 16AKP10

[Galen Hassen <rwekyes@gmail.com>]

The Lenovo IdeaPad Slim 5 16AKP10 (PCI SSID 17aa:38b6) uses the
Conexant SN6140 codec. The internal microphone is on pin 0x1a but
the BIOS configures it with pin default 0x95a60120, which includes
a jack detection bit that causes the kernel to treat it as an
unplugged external mic rather than a fixed internal mic.

Add a pin config quirk that overrides pin 0x1a to 0x95a60130,
setting the connectivity bits to indicate a fixed/always-connected
device. This allows the internal microphone to be correctly
identified and used.
