Subject: [PATCH] ASoC: amd: yc: Fix non-functional mic on Lenovo 82QF and 82UG

Like the Lenovo 82TL and 82V2, the Lenovo 82QF (Yoga 7 14ARB7) and 82UG
(Legion S7 16ARHA7) both need a quirk entry for the internal microphone to
function. Commit c008323fe361 ("ASoC: amd: yc: Fix a non-functional mic on
Lenovo 82SJ") restricted the quirk that previously matched "82" to "82V2",
breaking microphone functionality on these devices. Fix this by adding
specific quirks for these models, as was done for the Lenovo 82TL.

Fixes: c008323fe361 ("ASoC: amd: yc: Fix a non-functional mic on Lenovo 82SJ")
Closes: https://github.com/tomsom/yoga-linux/issues/51
