btintel: Prevent BRI traffic crosstalking with WiFi module

[En-Wei Wu]

[Impact]
BRI (Bluetooth Radio Interface) traffic from CNVr to CNVi was found causing
cross talk step errors to WiFi. Therefore, Bluetooth is turned on, the WiFi
may be disrupted by Bluetooth and thus not work reliably.

[Fix]
Apply the patch https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/bluetooth/btintel.c?id=c707097a446ce3d284bc9f05736dc4701d2b8168 on noble-oem-6.11

[Test Plan]
1. Compile noble-oem-6.11
2. Include Bluetooth FWs ibt-0190-0291-iml.sfi, ibt-0190-0291.ddc, ibt-0190-0291.sfi in /lib/firmware/intel/
( These FWs are not public yet. We're going to do SRU in the future once the FWs are landed on the upstream linux-firmrware)
3. Include WiFi FWs bz-b0-fm-c0-92.ucode in /lib/firmware/
( The same. These FWs are not public yet )
4. Boot the noble-oem-6.11 kernel
5. Test WiFi functionality.

[Where problems could occur]
The patch makes use of UEFI variable. If the variable is somehow not shown in the ROM, there might be some error.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-oem-6.11/6.11.0-1002.2 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done-noble-linux-oem-6.11'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-failed-noble-linux-oem-6.11'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Confirmed that linux-oem-6.11/6.11.0-1002.2 works well on my Intel BE201 device.
