ALSA: hda/realtek: Add ALC295 Dell TAS2781 I2C fixup

Browse Source 
This patch adds a new fixup for the ALC295 codec on some Dell
laptops that use the TAS2781 I2C amplifier.

The fixup correctly initializes the amplifier and pins, allowing
sound to work on all speakers of these devices.

The fixup chain is added to the relevant quirk entries for
Dell Polaris models.

[ adjusted for 6.17 kernel code by tiwai ]
