Subject: [PATCH] drivers/nvme: Add quirks for device 025e:f1ac

From: Ilya Guterman <amfernusus@...il.com>

This commit adds NVME_QUIRK_NO_DEEPEST_PS for
device [126f:2262], which belongs to device SOLIDIGM P44 Pro SSDPFKKW020X7

The device frequently have trouble exiting the deepest power state (5),
resulting in the entire disk unresponsive.

Verified by setting nvme_core.default_ps_max_latency_us=10000 and observing them behaving normally.
Also by running with the patch couldn't reproduce the issue after multiple wake up from sleeps.
Running without the patch again reprodcued the issue on the first wake from sleep.
