[PATCH v2] wifi: ath11k: add pm quirk for Thinkpad Z13/Z16 Gen1

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.
