* mwifiex: rebase PS5 IW620 patch for linux 7.1
- Rebase ps5-iw620.patch onto nxp-imx/mwifiex lf-6.18.20_2.0.0, which carries the cfg80211 API updates needed by Linux 7.1.
- Restore PS5 IW620 Wi-Fi module builds on the linux-7.1.y kernel by avoiding the net_device versus wireless_dev API mismatch.
- Target the PS5 IW620 PCIe path and disable unrelated SDIO/USB targets so the build does not pull unresolved sdio_* symbols.
- Export the PCI module alias so the PS5 IW620 module can autoload when the device is present.
- Keep the PS5 connected-state scan workaround, which fake-completes scans while associated to reduce firmware/driver instability.
- Preserve the legacy scan option behavior used by the PS5 load parameters.
- Update README fresh-build instructions to use the new NXP base ref.
* mwifiex: avoid IW620 scan and regulatory firmware quirks
The PS5 IW620 firmware accepts the core STA path but rejects the channel-attribute regulatory download with CHAN_REGION_CFG status 0x3. That shows up at boot as sub_id=0x200046 action=1 [FW_CMDRESP], even though the interface can still scan and associate.
Skip the channel attribute download for the PCIEIW620/PCIE9097 card type used by PS5 so the driver does not send the firmware command that fails on this platform.
Also treat a scan response with exactly zero optional TLV bytes as valid. NXP used a strict greater-than check, so normal scan responses without trailing TLVs were logged as scan_resp_size: Incorrect size of TLV buff size even when AP parsing completed successfully.
Keep the existing PS5 behavior that forces legacy scan mode and fake-completes connected-state scans for stability.
