This is v2 of the AW88399 HDA side codec driver series. Patches 1-5
from v1 (ASoC library preparation) were applied by Mark Brown and
merged into tiwai/sound via broonie/sound. This series contains the
remaining three patches.

Changes since v1:
* Fixed memory leak of acpi_subsystem_id string on probe error paths
  by switching to devm_kstrdup (bug reported by Sashiko, confirmed
  by Takashi Iwai)
* Added Acked-by tags from Rafael J. Wysocki and Ilpo Järvinen
  for the ACPI/platform changes

Patch 1 registers the AWINIC ACPI HID "AWDZ8399" with the ACPI
scan ignore list and the serial-multi-instantiate driver.

Patch 2 adds the HDA side codec driver: I2C bus driver and core
driver with HDA component binding, playback hooks, power management,
and per-model quirk matching.

Patch 3 enables the driver on Lenovo Legion Pro models with Realtek
ALC287 fixups and AW88399 per-model quirks.
