Extract the device-level functions from aw88399.c into a new shared library module (aw88399-lib.c) with a shared header at include/sound/aw88399.h, following the pattern established by CS35L41 (cs35l41-lib.c / include/sound/cs35l41.h) for chips that need both ASoC and HDA drivers. The shared header at include/sound/aw88399.h contains the register definitions, bit-field masks, hardware constants, device enums, the struct aw88399 definition, and the library function declarations. The ASoC-private header at sound/soc/codecs/aw88399.h is reduced to ASoC-specific definitions (PCM formats/rates, ALSA kcontrol helpers, calibration constants) and includes the shared header. The library contains the chip initialization, firmware loading, playback start/stop sequences, and all their internal dependencies (PLL checks, DSP management, volume control, calibration, CRC verification, etc.). The ASoC codec driver retains the ALSA controls, DAPM widgets, codec probe/remove, calibration service, and I2C bus driver registration. A new Kconfig symbol SND_SOC_AW88399_LIB is introduced. SND_SOC_AW88399 (the existing ASoC codec) selects it, ensuring no change for current users. The HDA side codec driver (introduced later in this series) selects the library without pulling in the full ASoC codec module. This avoids a build-time dependency on the full ASoC driver and follows the established pattern used by CS35L41 (SND_SOC_CS35L41_LIB) for chips with both ASoC and HDA drivers. Some library functions (DSP control, volume setting, mute, calibration updates, profile management, and status helpers) are used internally by the library's start/stop sequences but are also called directly by the ASoC driver's remaining code. These are exported from the library so the ASoC module can access them. This is a pure code movement with no functional changes. The moved functions are identical to their originals in aw88399.c.
