Add support for laptops that have CS35L41 connected to an
HDA codec by I2S and direct I2C/SPI connection to the CPU

Hardware:
 - The 16ACHg6 laptop has two CS35L41 amplifiers, connected
to Realtek ALC287 by an I2S bus and by and direct I2C to the CPU.
 - The ALC287 codec is connected to the CPU by an HDA bus.
 - The CS35L41 has a DSP which will require firmware to be loaded.

Architecture:
 - Creation of a library of shared functions for CS35L41 ASoC and HDA
 - HDA codec driver (RealTek) and CS35L41 HDA driver are combined
 by using component binding, where it uses device names to find the
 components and bind to the master
 - The HDA CS35L41 driver applies pre-defined registers sequences
 for each action in playback for HDA Sound card

Changes from V2:
 - Not an RFC
 - Create a new HDA driver for CS35L41 instead of using the ASoC one
 - Use component binding and device names to find the CS35L41 driver
 - Create a shared library for ASoC and HDA CS35L41 drivers

Lucas Tanure (11):
  ASoC: cs35l41: Set the max SPI speed for the whole device
  ASoC: cs35l41: Convert tables to shared source code
  ASoC: cs35l41: Move regmap config struct to shared code
  ASoC: cs35l41: Create function for init array of Supplies
  ASoC: cs35l41: Move cs35l41_otp_unpack to shared code
  ASoC: cs35l41: Move power initializations to reg_sequence
  ASoC: cs35l41: Create shared function for errata patches
  ASoC: cs35l41: Create shared function for setting channels
  ASoC: cs35l41: Create shared function for boost configuration
  hda: cs35l41: Add support for CS35L41 in HDA systems
  ACPI / scan: Create platform device for CLSA0100 ACPI nodes

This suggests that both amplifiers are using the same GPIO pin as shared
IRQ, is that correct ? Can you share an acpidump of the laptop's DSDT tables ?

DSDT attached.
Yes, both amps share the same IRQ gpio.

Can we keep it sorted, please?
Ditto for the other driver.
