ALSA: hda/realtek: Add quirk for Lenovo IdeaPad Slim 3 15ABR8

Browse source

The internal microphone on Lenovo IdeaPad Slim 3 15ABR8 (subsystem
17aa:3862) exhibits severe distortion at default gain levels. The
Capture Volume is fixed at 63 (max) and cannot be lowered without
explicit userspace intervention. The existing fixup
ALC269_FIXUP_LIMIT_INT_MIC_BOOST limits the gain range and resolves
the issue.
