ALSA: hda/tas2781: add TAS2563 support for 14ARB7

Browse Source 
The INT8866 belongs to the Lenovo Yoga 7 Gen 7 AMD 14ARB7
laptop. It has two TAS2563 amplifier. Add the PNP ID
and calibration functions to handle them.

ACPI excerpt:

             })
             Return (RBUF) /* \_SB_.I2CD.TAS_._CRS.RBUF */
        }
