[PATCH v4] Bluetooth: btusb: Add MediaTek MT7925-B22M support ID 0x13d3:0x3604

[Alexander Hall]

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.

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:

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
