Since the order of the amps in the ACPI determines the device name,
and the ACPI order may change depending on hardware configuration,
use UID to dynamically compute the dai links, allowing dynamic
assignment of the name_prefix.
The UIDs for these amps in ACPI are fixed, and map to a name_prefix,
where:
UID 0x0 -> WL
UID 0x1 -> WR
UID 0x2 -> TL
UID 0x3 -> TR

A warning is a bit strong if some valid configurations don't expose all

The intent was to support 2 or 4, rather than any number of amps, in

I'll change this to a debug message, but also add an error if there is not
2 or 4 amps found.
