Add aw88399_dev_set_channel() to the shared library so that the HDA side
codec driver can set the amplifier's channel assignment without
including the aw88395 device header directly.
The AW88399's struct aw_device is defined in aw88395_device.h, which
lives under sound/soc/codecs/aw88395/. Without this accessor, the
HDA driver would need a cross-subsystem relative include path to
access the channel field. Providing a setter in the library keeps the
interface clean and avoids coupling the HDA driver to ASoC-internal
headers.

Add a fw_needs_reload flag to struct aw88399 that, when set, causes
aw88399_start to perform a full DSP firmware upload instead of
assuming the firmware binary is already present in memory.
After system sleep, the AW88399 loses its memory contents. The
existing start sequence assumes the firmware binary persists from
initialization and only uploads register configuration and DSP
config (AW88399_DSP_FW_UPDATE_OFF). When memory is empty, this causes
the subsequent CRC check to fail, triggering the retry mechanism in
aw88399_start_pa which re-uploads the firmware on the second
attempt.
While the retry mechanism recovers correctly, it produces
misleading error-level log messages on every resume cycle. The
fw_needs_reload flag allows the HDA side codec driver to signal
that a full firmware reload is needed after resume, eliminating
the spurious CRC failures.
The flag defaults to false via kzalloc, preserving the original
behavior for existing ASoC users. No existing code path sets this
flag; it will be set by the HDA side codec driver's system suspend
handler.

Add a bsts_unreliable flag to struct aw88399 that, when set, causes
the startup status check (aw_dev_check_sysst) to skip the BSTS
(boost startup finished) requirement.
On some hardware, the BSTS bit in the SYSST register (0x01, bit 9)
does not reliably assert even during normal audio playback. Register
inspection on affected Lenovo Legion hardware shows both amplifiers
reporting BSTS=0 on both channels despite clean audio output.
Per the AW88399 datasheet, BSTS indicates boost startup completion.
If BSTS never reliably sets to 1, the chip is never allowed to start
by aw_dev_check_sysst, regardless of whether the boot failure is genuine.
The new flag defaults to false via kzalloc, preserving the original check
behavior for all existing users. No existing code path sets this flag;
it will be set by the forthcoming HDA side codec property driver for
affected hardware.

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.
