Recent versions of udev cause synchronous firmware loading from the
probe routine to fail because the request to user space times out.
The original fix for b43legacy (commit a3ea2c76) moved the firmware
load from the probe routine to a work queue, but it still used synchronous
firmware loading. This method is OK when b43legacy is built as a module;
however, it fails when the driver is compiled into the kernel.

This version changes the code to load the initial firmware file
using request_firmware_nowait(). A completion event is used to
hold the work queue until that file is available. The remaining
firmware files are read synchronously.

This adds support for bcma wifi core revision 17 which is found on
BCM4716/4717/4718 SoCs. The firmware version 610.812 for brcmsmac found
in linux-firmware does not support these cores, but a firmware
generated with b43-fwcutter from the proprietary broadcom wireless
driver works with these chips. This wifi core contains a revision 5
N-PHY and a revision 7 radio of type 0x2056.

This reverts commit f74b9d36.

Turns out reverting commit a240dc7b
"ath9k_hw: Updated AR9003 tx gain table for 5GHz" was not enough to
bring the tx power back to normal levels on devices like the
Buffalo WZR-HP-G450H, this one needs to be reverted as well.

This revert improves tx power by ~10 db on that device
