[PATCH v3 10/11] soundwire: amd: guard DAI PCM caps by acp_rev in register_dais()

[Vijendar Mukunda]

Replace the bare stream->rates and stream->formats assignments in
amd_sdw_register_dais() with an explicit switch/case on acp_rev
covering ACP63, ACP70, ACP71, and ACP72. An unrecognised revision
now returns -EINVAL at DAI registration time rather than silently
inheriting capabilities that may not apply to future hardware.
