Without them iwlwifi cannot correctly recognize the device on systems with Comet Lake cpu. [Fix] These changes are cherry-picked from either mainline kernel or backport-iwlwifi. Firmware blob iwlwifi-QuZ-a0-jf-b0-*.ucode is also necessary. [Test] Verified on hardware 02f0:4234 with fw rev 48. [Regression Potential] Low.
