Device role is always started along with ROC.
Couple them together by introducing new wl12xx_start_dev
and wl12xx_stop_dev functions.

By using these functions, we solve a bug that occured during
channel switch - we started the dev role on one channel, and
ROCed on a different one.

Injected packets are sent with no vif, causing the wl12xx
to NULL-dereference in multiple places.

Furthermore, injected packets are currently not sent at all,
as system_hlid doesn't belong to any specific role, so
wl1271_skb_dequeue() never return its packets.

Handle both these problems.

There's no need to have the bus name included in the platform device
name that we create.  The core driver doesn't need to know about the
type of bus it uses.  Any differences between the buses that need to
be handled differently in the core, can be passed in the platform data
(as the pwr_in_suspend boolean does).

Use "wl12xx" for the device name in both bus drivers.  Rename the
platform driver name to "wl12xx_driver", just to differentiate from
the platform device names.

To prevent a useless dependency between the spi module and the wl12xx
module, we need to replace the wl1271_error macros with dev_err.

At the same time, remove the SPI data hexdump, since this produces way
too much data and is not particularly useful.  There's no
print_hex_dump() equivalent for dynamic debug, so it's hard to control
when the dumps are printed out.

Separate the debugging macros and other definitions to a new debug.h
file.  This is be needed because the sdio and spi modules don't need
to depend on the wl12xx module anymore, but still need to include
wl12xx.h.  Currently they do depend on it, because of the debugging
global that wl12xx exports.  A future patch will remove this
dependency.

This module has been causing more trouble than being useful.  It only
tests the SDIO speed by connecting to the wl12xx chip and does some
throughput calculations.  It is an ugly quick hack and, if we really
want to have it as part of wl12xx we need to clean it up and implement
it properly.

A tarball of the code has been created and posted here, with some
instructions:
