There is no driver for the Broadcom 1570 webcam so we need to write one.
I've been working on this for a while but it's a lot of work. The Webcam
is basically a SoC sitting on the PCIe bus. So we need to boot the SoC
with some firmware and then figure out how to talk to it. I'm currently
fiddling with the DRAM timings.

The code is available at https://github.com/patjak/bcwc_pcie
