wireless: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

Revert "cw1200: Don't perform SPI transfers in interrupt context"
This reverts commit aec8e88c947b7017e2b4bbcb68a4bfc4a1f8ad35.
This solution turned out to cause interrupt delivery problems, and
rather than trying to fix this approach, it has been scrapped in favor
of an alternative (and far simpler) implementation.

cw1200: Don't perform SPI transfers in interrupt context
When we get an interrupt from the hardware, the first thing the driver does
is tell the device to mask off the interrupt line. Unfortunately this
involves a SPI transaction in interrupt context. Some (most?) SPI
controllers perform the transfer asynchronously and try to sleep.
This is bad, and triggers a BUG().
So, work around this by using adding a hwbus hook for the cw1200 driver
core to call. The cw1200_spi driver translates this into
irq_disable()/irq_enable() calls instead, which can safely be called in
interrupt context.
Apparently the platforms I used to develop the cw1200_spi driver used
synchronous spi_sync() implementations, which is why this didn't surface
until now.
Many thanks to Dave Sizeburns for the inital bug report and his services
as a tester.

cw1200: Eliminate the ETF debug/engineering code.
This is only really useful for people who are bringing up new hardware
designs and have access to the proprietary vendor tools that interface
with this mode.
It'll live out of tree until it's rewritten to use a less kludgy interface.

cw1200: Rename 'sbus' to 'hwbus'
This avoids problems when building on SPARC targets due to the driver
calling the bus abstraction layer 'sbus'. Not that any SBUS-sporting
SPARC targets are likely to have an SDIO controller, but this is the
correct thing to do.
