Public bug reported:
[Impact]
Ubuntu currently doesn't support wifi 6e, but wifi 6e AP will be discovered
while scanning. User can't get connected to those wifi 6e AP, so disable
UHB(ultra high band) in the driver to avoid scanning those bands.
[Fix]
Marks all AX210 and AX211 cards to disable UHB.
[Test]
Verified the system with AX211 card and confirm it can't discover wifi 6e bands.
[Where problems could occur]
Disable non-supported bands won't introduce any regression.
