We free name "dev" for something generic (like dev abstraction layer).
Additionaly code is cleaner now, especially magic dev->dev-dev chains.

Devices which use LO enabled bit are covered by b43legacy

The routine b43_is_hw_radio_enabled() has long been a problem.
For PPC architecture with PHY Revision < 3, a read of the register
B43_MMIO_HWENABLED_LO will cause a CPU fault unless b43_status()
returns a value of 2 (B43_STAT_STARTED) (BUG 14181). Fixing that
results in Bug 14538 in which the driver is unable to reassociate
after resuming from hibernation because b43_status() returns 0.

The correct fix would be to determine why the status is 0; however,
I have not yet found why that happens. The correct value is found for
my device, which has PHY revision >= 3.

Returning TRUE when the PHY revision < 3 and b43_status() returns 0 fixes
the regression for 2.6.32.

This patch fixes the problem in Red Hat Bugzilla #538523.

"b43: Fix PPC crash in rfkill polling on unload" fixed the bug reported
in Bugzilla No. 14181; however, it introduced a new bug. Whenever the
radio switch was turned off, it was necessary to unload and reload
the driver for it to recognize the switch again.

This patch fixes both the original bug in #14181 and the bug introduced by
the previous patch. It must be stated, however, that if there is a BCM4306/3
with an rfkill switch (not yet proven), then the driver will need an
unload/reload cycle to turn the device back on.

The LP (and probably N) PHY has the same radio disabled bit as
the higher-revision A and G PHYs.

This ports the b43/legacy rfkill code to the new API offered
by cfg80211 and thus removes a lot of useless stuff.
