iwlwifi BE200 probe fails with -22 (EINVAL) on kernel 6.18.33+rpt-rpi-2712

Reproduce the failure on kernel 6.18.33+rpt-rpi-2712 and compare it with the working 6.12.75+rpt-rpi-2712, starting from the iwlwifi probe path and its PCI ID or configuration handling. Use the supplied lspci and dmesg output to trace the BE200 revision; done means the card initializes without the -22 probe error and the regression is covered by verification across both kernels.

Describe the bug

Intel BE200 Wi-Fi 7 card fails to initialize on kernel 6.18.33+rpt-rpi-2712 with probe with driver iwlwifi failed with error -22. This is a regression — the card worked on 6.12.75+rpt-rpi-2712.
This issue has previously occurred when iwlwifi was dropped from the kernel config (see #6672). However in this case the module is present but probe fails with EINVAL, suggesting a PCI ID or config mismatch rather than a missing module.
Hardware

Board: Raspberry Pi 5
Wi-Fi card: Intel Wi-Fi 7 BE200 (PCI ID 8086:272b, rev 1a)
PCI address: 0001:01:00.0

Software

Broken kernel: 6.18.33+rpt-rpi-2712 (1:6.18.33-1+rpt1)
Last working kernel: 6.12.75+rpt-rpi-2712 (1:6.12.75-1+rpt1)

Steps to reproduce the behaviour

Install 6.18.33+rpt-rpi-2712 and connect Intel BE200 adapter on M2.key pihat.

Additional context

The card works correctly on 6.12.75+rpt-rpi-2712
No iwlwifi-related PRs were merged in the 6.18.33 or 6.18.34 bumps
Related previous issue: #6672 (iwlwifi dropped from config in 6.12)
rfid=0x112200 and rev=0x472 are logged but probe still fails — suggests possible missing or incorrect PCI ID entry for this hardware revision in the 6.18 driver
