ALSA: hda/realtek - Limit int mic boost on Acer Aspire E5-575T

commit 495dc7637cb5ca8e39c46db818328410bb6e73a1 upstream.

The Acer Apire E5-575T laptop with codec ALC255 has a terrible
background noise comes from internal mic capture. And the jack
sensing dose not work for headset like some other Acer laptops.

This patch limits the internal mic boost on top of the existing
ALC255_FIXUP_ACER_MIC_NO_PRESENCE quirk for Acer Aspire E5-575T.
