update iwx(4) firmware to -67

[Stefan Sperling]

This patch updates iwx(4) to new firmware images (API version -67).

Intel has published a related security advisory:
https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00509.html

Make sure to get a fresh kernel from -current sources and update
to iwx-firmware-20211101 with fw_update before trying this patch.
The new firmware version shows as "fw ver 67.8f59b80b.0" in dmesg.
I have tested on AX200 and AX201 and I am not seeing any issues.

iwx(4) devices which are using the iwx-Qu-c0-hr-b0-63 image did
not receive a firmware update. I cannot tell why.

ok?
