Hector Martin aa96d6aa75 nvme-apple: add NVME_QUIRK_IDENTIFY_CNS quirk to fix regression
From the get-go, this driver and the ANS syslog have been complaining
about namespace identification. In 6.2-rc1, commit 811f4de034 ("nvme:
avoid fallback to sequential scan due to transient issues") regressed
the driver by no longer allowing fallback to sequential namespace scans,
leaving us with no namespaces.

It turns out that the real problem is that this controller claiming
NVMe 1.1 compat is treating the CNS field as a binary field, as in NVMe
1.0. This already has a quirk, NVME_QUIRK_IDENTIFY_CNS, so set it for
the controller to fix all this nonsense (including other errors
triggered by other CNS commands).

Fixes: 811f4de034 ("nvme: avoid fallback to sequential scan due to transient issues")
Fixes: 5bd2927ace ("nvme-apple: Add initial Apple SoC NVMe driver")
