[ Upstream commit 6b6f7263d626886a96fce6352f94dfab7a24c339 ]

Replace DMI_EXACT_MATCH with DMI_MATCH for Lenovo SKU entries (21YW,
21YX) so the quirk applies to all variants of these models, not just
exact SKU matches.

Add ASOC_SDW_ACP_DMIC flag alongside ASOC_SDW_CODEC_SPKR in driver_data
for these Lenovo platform entries, as these platforms use ACP PDM DMIC
instead of SoundWire DMIC for digital microphone support.
