[PATCH] ALSA: hda/realtek: Fix speakers on MECHREVO WUJIE Series

[Chen Bowen]

The internal speakers on the MECHREVO WUJIE Series are silent,
while the headphone output works correctly.

The BIOS reports NID 0x1b on the Realtek ALC233 codec as
unconnected with pin configuration 0x411111f0. However, the pin
is connected to an internal speaker.

Overriding NID 0x1b with 0x90170150 makes the HDA generic parser
detect both 0x14 and 0x1b as speaker outputs and restores internal
speaker playback.

Add a pin configuration fixup for the affected PCI SSID c011:1d05.

Tested on a MECHREVO WUJIE Series laptop with board
WUJIE Series-Lark4-LNL and firmware EM_LNL326_V1.0.23.
