staging: add Broadcom Crystal HD driver

This patch supersedes the earlier ones sent by Manu Abraham to add
the Broadcom Crystal HD driver to the staging tree, per discussion
with him about it. I've been working with Broadcom's Naren Sankar
on this driver for a number of months, and had already talked Naren
about submitting this on Broadcom's behalf, didn't expect anyone
else to jump on submitting it as quickly as Manu did. ;)

This version is a one-shot deal, incorporating the original driver,
Manu's coding style clean-ups, udev device creation support from
Edgar 'gimli' Hucek, and a number of other small tweaks from myself
and Scott Davilla, the other individual who has been working closely
on this code with Naren and I.

I've tested this iteration of the code lightly on a mini pci-e board
in a ThinkPad T61p running x86_64 Fedora 12, with the expected results,
and will test further on other systems with other variants of the card
(I have three varieties of this device currently in hand). Scott has
also tested on assorted primarily i686 varieties of Ubuntu, and Naren
has tested with both Fedora and Ubuntu, iirc.

Note: only the 70012 is currently supported by this driver, 70015
support will follow later. Also note that Blu-Ray support isn't
enabled (at the firmware level), due to misc fun related to the
BD encryption scheme, DRM, etc. :\

I *do* have a git tree containing the driver, lib, gst plugin and
firmware that I'm working from at the moment[*], as there are inter-
dependencies between the driver and lib, and the driver can be used
with kernels going a ways back (I've only tested back to 2.6.18 as
it exists in Red Hat Enterprise Linux 5). I'm exporting from there,
into a linux-next tree, then generating patches from there. The goal
is to feed everything upstream as quickly as possible, but there are
users who want this code for earlier kernels too...

The firmware will be submitted for inclusion in dwmw2's linux-firmware
tree once there is a suitable redistribution-no-modification type of
license on it (I believe Naren is working with Broadcom legal to get
that in place).

Changelog from initial Broadcom release to here:
