There's a similar configuration with another bug report, see
https://bugzilla.kernel.org/show_bug.cgi?id=221782
the symptoms are different but clearly this configuration isn't well
handled just yet.

It's my understanding that the function topologies are expected now,
machine table entries are no longer required.
In the dmesg log, what's suspicious to me is those lines:
[ 225.115571] acpi device:1d: function type only supported as DisCo
constant
[ 225.115930] acpi device:1f: function type only supported as DisCo
constant
[ 225.116271] acpi device:21: function type only supported as DisCo
constant
[ 225.116612] acpi device:23: function type only supported as DisCo
constant
[ 225.117313] acpi device:25: SDCA function UAJ (type 6) at 0x1
[ 225.117317] acpi device:26: SDCA function SmartMic (type 3) at 0x2
[ 225.117320] acpi device:27: SDCA function HID (type 10) at 0x3
not sure why the 4 amps report information that's not well parsed, if
the amps were recognized as such you'd see a clearer log. For now only
the rt712 is handled correctly.
