PATCH v5 1/1 Bluetooth: btusb: Add MediaTek MT7925-B22M support ID 0x13d3:0x3604

This patch fixes bluetooth support on the MediaTek MT7925 WiFi 7 + BT 5.3 M.2 chipset that I purchased from aliexpress (and which arrived today). The PCB states that it is an MT7925B22M.

Device from /sys/kernel/debug/usb/devices:

High fidelity images I took of the chip itself for future reference:

Webpage the chip was purchased from, note it is different from the images taken:
https://web.archive.org/web/20240620021119/https://www.aliexpress.
us/item/3256806821207897.html

---
Changes from v1:
It was suggested that the (now removed) aliexpress link be run through
archive.org, however aliexpress is incompatible with waybacks scraping tool, and as an alternative I have taken high resolution images of the actual chip I received and put them on archive.org.
The prefix of this patch was changed to Bluetooth: as suggested Maintainers and open lists have been auto CC'd as suggested, via
get_maintainers.pl
Changes from v2:
the commit name has been updated to include the device:vendor id to be clearer
web archive eventually came through so I have readded the link to that aswell
Changes from v3:
tabs replaced with spaces, Signed-off-by now matches From sender
Changes from v4:
remove trailing whitespace that gitlint failed on

I'm confused on why TestRunner_mgmt-tester is now failing, it seems to be a test on the

patch itself (and on v3 of this patch it did not fail, which has an identical codechange).

I do not wish to resend an identical patch and waste CI time if there is indeed something wrong with the patch,

but I would like to be advised if this is a spurious/unrelated failure, and if so should I resend the patch? or is there a mechanism to rerun these tests
