[RFT][PATCH] b43: HT-PHY: disable TX power control on BCM94331X19

["Rafał Miłecki" <zajec5@gmail.com>]

In case of BCM94331X19 default TX state seems to perform better than
after our configuration. Disable TX power control for now on this card
(until fixing power control).

David: could you test this for me, please? Can you see that
> BCM94331X19 detected, disabling TX power control for better performace
message in dmesg? Does it brings you back a better perofmrnce?

Simply apply it on top of wireless-testing.
