[PATCH 2/5] ASoC: amd: acp: add ACP70 SoundWire machine entry for ASUS RC74XA

[Matthew Schwartz <matthew.schwartz@linux.dev>]

The ROG Xbox Ally X20 (RC74XA) has two TAS2783 amps on link 0 with
unique IDs 0x8 and 0xB and an RT721 on link 1. No table entry describes
that layout, so machine selection falls through to acp70_rt721_only and
routes speaker playback to the unused RT721 amp endpoint.

Add a two-link entry ahead of acp70_rt721_only with the RT721 limited
to its jack and DMIC endpoints.
