[PATCH] ASoC: Intel: soc-acpi: add SoundWire config for ASUS P5405CAA

[Antonio Di Lorenzo <antoniodilorenzonap@gmail.com>]

The ASUS ExpertBook P5 P5405CAA uses two TAS2783 speaker
amplifiers on SoundWire link 1 and an RT721 codec on link 3.

Add the corresponding SoundWire ADR devices and link description
so the sof_sdw machine driver can select the correct configuration.

RT721 AIF1 is used for the headset jack and AIF3 for the DMIC,
while AIF2 is unused when external speaker amplifiers are present.

Use function topology selection for this configuration.
