[RESEND PATCH v2] ALSA: hda/tas2781: Create a common header for both spi and i2c tas2781 hda driver

From: Shenghao Ding
Date: Tue Apr 15 2025 - 03:09:56 EST


Move the common macro definition of kcontrols into a common header.

Signed-off-by: Shenghao Ding <shenghao-ding@xxxxxx>

---
v2:
- Follow IWYU principle, add sound/asound.h into the header file.
v1:
- Revise the year of spi and i2c tas2781 hda drivers.
- Create a common header for both spi and i2c tas2781 hda driver to define
the common macros and declare the common functions.
