gianfar driver: eliminate compiler warnings and unnecessary macros
This patch eliminates the warning of unused return values when the driver
registers it sysfs files. Now the driver will print an error if it is
unable to register the sysfs files.
It also eliminates the macros used to wrap the DEVICE_ATTR macro and the
device_create_file function call. The macros don't reduce the number of
lines of source code in the file and the name munging makes is so that
cscope and friends don't see the references to the functions. It's better
to just call the kernel API directly.
While we're at it, the DEVICE_ATTR instances have been moved down to
be grouped with the functions they depend on.

b43: Changes to enable BCM4311 rev 02 with wireless core revision 13
The BCM94311MCG rev 02 chip has an 802.11 core with revision 13 and
has not been supported until now. The changes include the following:
(1) Add the 802.11 rev 13 device to the ssb_device_id table to load b43.
(2) Add PHY revision 9 to the supported list.
(3) Change the 2-bit routing code for address extensions to 0b10 rather
than the 0b01 used for the 32-bit case.
(4) Remove some magic numbers in the DMA setup.
The DMA implementation for this chip supports full 64-bit addressing with
one exception. Whenever the Descriptor Ring Buffer is in high memory, a
fatal DMA error occurs. This problem was not present in 2.6.24-rc2 due
to code to "Bias the placement of kernel pages at lower PFNs". When
commit 44048d70 reverted that code, the DMA error appeared. As a "fix",
use the GFP_DMA flag when allocating the buffer for 64-bit DMA. At present,
this problem is thought to arise from a hardware error.
