This patch extends the use of the brcmfmac driver with support for
chipsets with a USB host interface. The first chipsets supported are
the bcm43235, bcm43236, and bcm43238 for which firmware has been
submitted.
This driver change has been successfully built for x86, x86_64,
ppc64, arm_le, and mips_be.
It has been tested successfully on x86 and x86_64.

It appears that you can only read the sprom contents with aligned 16-bit
reads: anything else causes at least some versions of the broadcom
chipset to abort the PCI transaction, returning 0xff.
This apparently doesn't trigger very often, because most setups don't
use an external srom chip, and the OTP sprom loading doesn't have this
issue. But at least the current 11" Macbook Air does trigger it, and
wireless communications were broken as a result.

When there is data available in dongle for driver to fetch, an
interrupt will be triggered and both SDIO function 1 and 2 will be
flagged by default in bcm4329. These two interrupt flags are
identical and only need to be handled once. Since there is no way
to turn off one flag from the dongle side, a dummy handler for
function 2 interrupt is placed.

A new feature in the dongle firmware requires a handshake during
firmware intialization. The request is sent in event packets which the
host driver is not able to handle before any net device registered.
Discard those packets as the context for handling it is missing.
The initialization handler will be added as part of feature support
code in the future.

The functions in the receive patch of the fullmac now use sk_buff
list and skb_queue_xx() functions instead of dealing with list pointers
in the sk_buff directly.

The function brcmu_format_hex() filled a string buffer with byte
values from a data buffer. The calling function used this string
buffer in a printk. Now the calling function uses the kernel
function print_hex_dump_bytes().

Obviously the phy api should be used to interface with the phy. In
rate.h a table within phy was accessed directly by declaring the
table extern in rate.h itself. This patch fixes this using the
provided api function to obtain the table reference. This bypass
was found by a sparse warning on the table not being defined static.

The data from the sprom consists of u16 values stored in little
endian notation over which a crc8 was determined. To validate this
the buffer needed to be converted for big-endian systems. Reading
the sprom data is now done per byte so conversion is only done
after a successful crc8 check.
