compat: add br_port_exists() and ask for inclusion upstream

The br_port_exists() call is used internally on private bridge
code on net/bridge/ to check if a netdevice is a bridge port.
The way to check if a netdevice is a bridge port has changed
for 2.6.36 from checking the netdev->br_port pointer to
checking for a IFF_BRIDGE_PORT flag on the netdev->priv_flags.

Instead of requiring backport code to ifdef the checks lets
move the private br_port_exists() to a public header accessible
by drivers and consistantly use it to check for the bridge
port.

I'll submit a patch upstream to move br_port_exists() to a public
header so that we don't have to later even require a patch on
backported code. We'll see if it gets accepted though.

Backport the new firmware_class from > 2.6.33 down to 2.6.23

My main concern with this backport was the usage of the
core driver "base.h" but as it turns out firmware_class doesn't
even need it. This allowed the backport to go through.

This new backport allows drivers which use the new modified firmware
API request_firmware_nowait() on older kernels. You should not
need to chagne the your request_firmware_nowait() calls at all;
the compat-2.6.32.h header ensures that your calls get mapped
to compat_request_firmware_nowait()

compat: build pccard and pcmcia condituinaly

If the kernel does not include pcmcia, compat.o should not relay on
methods provided by it.

compat: autoconf.h moved from linux/ to generated/ with kernel 2.6.33

Changed the headers, because autoconf.h moved from linux/ into
generated/

All compat-2.6.XX.h files are included by compat-2.6.h, so only
compat-2.6.h needs to include autoconf.h. There is no situation known to
me where you want to include any compat-2.6.XX.h file directly.

This fixes build with kernel 2.6.33, without it complains about a
missing import:

Add module load print to know where we backported from

For stable kernels this will be more important. I'll soon start
a branch based on new kernel releases so if anyone wants to
base their code only up to a specific point release they can use
that.
