b43: Automatically probe for opensource firmware

First probe for proprietary firmware and then probe for opensource firmware.
This way around it's a win-win situation.
1) If proprietary fw is available, it will work.
2) If opensource firmware is available, but no proprietary (Distros can only ship open fw)
   it might work.
3) If both open and proprietary are available, it will work, because it selects
   the proprietary. We currently don't prefer the open fw in this case, because it doesn't

rtl8187: Fix driver to return TX retry info for RTL8187L

Current code for the RTL8187 is not returning valid retry information, thus the
rate-setting mechanism is not functioning. As a further complication, this info
is only obtained by reading a register, which cannot be read while in interrupt
context.

This patch implements the TX status return to mac80211 through the use of a
work queue.

One additional problem is that the driver currently enables the rate fallback
mechanism of the device, which conflicts with the mac80211 rate-setting
algorithm. This version of the patch disables rate fallback.
