ALSA: hda/realtek - Fix overridden device-specific initialization
The recent change to shuffle the codec initialization procedure for Realtek via commit 607ca3bd220f ("ALSA: hda/realtek - EAPD turn on later") caused the silent output on some machines. This change was supposed to be safe, but it isn't actually; some devices have quirk setups to override the EAPD via COEF or BTL in the additional verb table, which is applied at the beginning of snd_hda_gen_init(). And this EAPD setup is again overridden in alc_auto_init_amp(). For recovering from the regression, tell snd_hda_gen_init() not to apply the verbs there by a new flag, then apply the verbs in alc_init().
