[SRU][R][PATCH 1/1] ALSA: hda/tas2781: Fix sound abnormal issue on some SPI device

[AceLan Kao]

From: Baojun Xu <baojun.xu at ti.com>

BugLink: https://bugs.launchpad.net/bugs/2149770

In the SPI driver probe, the chip ID must be set to TAS2781. Without this
initialization, calibration data fails to load correctly, causing audio
abnormalities on some devices.
And update the register bulk read API to handle the distinct requirements
of SPI and I2C devices.

Fixes: 05ac3846ffe5 ("ALSA: hda/tas2781: A workaround solution to lower-vol issue among lower calibrated-impedance micro-speaker on TAS2781")
