Sounds like we prefer to have this under drivers/ instead of device/.
Also move all MIPI-related headers out from device/ into their own
directory.

This patch adds new soundwire device ALC1308
The codec properties are filled out as best as possible
with the datasheet as a reference.
The ACPI address for the codec is calculated with the information in
the codec driver combined with the devicetree.cb hierarchy where the
link and unique IDs are extracted from the device path.
The unique ID is calculated from schematics by referring to ASEL[1:0]
strap settings. Datasheet of ALC1308 provides info about the mapping of
ASEL strap settings to unique ID
For example this device is connected to master link ID 1 and has strap
settings configuring it for unique ID 2.
chip drivers/soundwire/alc1308
register "desc" = ""Left Speaker""
device generic 1.2 on end
end
Bug=None
Test=Build and boot on TGLRVP.Extract SSDT and confirm that the entries for
PCI0.HDAS.SNDW are present for ALC1308
Test speaker out functionality

Individual drivers check whether the concerned device is enabled before
filling in the SSDT. Move the check before calling acpi_fill_ssdt() and
remove the check in the individual drivers.

Bug=None
Test=Enabled the device on TGLY RVP and tested that the codec is
reflected in SSDT. Checked sound card binding works
and soundwire drivers are enabled in kernel.

The ALC5682 headset codec can be connected over SoundWire and be
configured for mainboards to use:
- Data Port 0 and Bulk Register Access is supported
- Data Ports 1-4 are supported as both source and sink
The data port and audio mode properties are filled out as best as
possible with the datasheet as a reference.
The ACPI address for the codec is calculated with the information in
the codec driver combined with the devicetree.cb hierarchy where the
link and unique IDs are extracted from the device path.
For example this device is connected to master link ID 0 and has strap
settings configuring it for unique ID 1:
chip drivers/soundwire/alc5682
register "desc" = ""Headset Codec""
device generic 0.1 on end
end
This driver was tested with the volteer reference design by booting
and disassembling the runtime SSDT to ensure that the devices have the
expected address and properties.

The MAX98373 smart speaker amp can be connected over SoundWire and be
configured for mainboards to use:
- Data Port 0 and Bulk Register Access is not supported
- Data Port 1 is the 32bit data input for the speaker path
- Data Port 3 is the 16bit data output for I/V sense ADC path
The data port and audio mode properties are filled out as best as
possible with the datasheet as a reference.
The ACPI address for the codec is calculated with the information in
the codec driver combined with the devicetree.cb hierarchy where the
link and unique IDs are extracted from the device path.
For example this device is connected to master link ID 1 and has strap
settings configuring it for unique ID 3.
