[ Upstream commit 4015b1972763d7d513172276e51439f37e622a92 ]

Z16 Gen1 has the wakeup-from-suspend issues from [1] but was never added
to the appropriate quirk list. I've tested this patch on top of 6.18.2,
it fixes the issue for me on 21D4

Mark Pearson provided the other product IDs covering the second Z16 Gen1
and both Z13 Gen1 identifiers. They share the same firmware, and folks
in the bugzilla report do indeed see the problem on Z13.
