Bug description:
  [kernel SRU Justification]

  [Impact]

  Mediatek MT7925 WiFi/Bluetooth not supported yet.

  [Fix]

  For WiFi, there are tons of patches to be backported from upstream
  kernel v6.7 due to a massive refactoring was done to integrate
  multiple mt79xx drivers into one before landing support for mt7925.
  While these changes, mostly clean cherry-picks, are tied to each
  other, and separating them may cause more efforts in the future, a
  huge patchset of total number 144 is proposed.

  For Bluetooth, upstream commit 4c92ae75ea7d ("Bluetooth: btusb: Add
  support Mediatek MT7925") is required.

  [Test Case]

  Initial hardware support. One should be able to find WiFi/BT
  interfaces up available along with proposed kernels.

  [Where problems could occur]

  Features for MT7925 are not all available at this moment, and expect
  more fixes for every corner case.

  [Other Info]

  MT7925 is supported since v6.7, and we need it for oem-6.5 as well.
  Nominate for Jammy and Noble.
