ALSA: hda/realtek: Add ALC235 support for headset mode

Browse Source 
The ALC235 (0x10ec0235) is registered as the ALC255 codec variant in
patch_alc269(), but the headset mode functions were missing a case
for it, so the CTIA/OMTP jack type detection and routing never ran
on this codec. As a result, a plugged-in headset is detected (jack
presence works) but the microphone signal is never routed, leaving
the capture stream permanently silent.

Verified on an ASUS M5451GA laptop (HDA:10ec0235,10431814): with the
ALC255 coef sequence applied, the headset microphone works correctly.
