update - new hal flag to force a full chip reset

[Adrian Chadd]

Just stick with the AR9220/AR9280 NICs. I have to fix this stuff,
right? So unless you absolutely, positively require stuff right now
(and if you do, grab an AR9160), stick with the AR9220/AR9280.

The AR9220/AR9280 in 5ghz mode works just fine in my testing.

I haven't (re) tested the AR9285/AR9287 in congested 2.4ghz mode. I'll
try to do that this week.
