Subject: [PATCH] ALSA: hda/realtek: Fix noise from speakers on Lenovo IdeaPad 3 15IAU7

Fixes: 70794b9563fe ("ALSA: hda/realtek: Add more codec ID to no shutup pins list")
Fix noise from speakers connected to AUX port when no sound is playing.
The problem occurs because the `alc_shutup_pins` function includes
a 0x10ec0257 vendor ID, which causes noise on Lenovo IdeaPad 3 15IAU7 with
Realtek ALC257 codec when no sound is playing.
Removing this vendor ID from the function fixes the bug.
