Add a CAM-Newbus SDIO support module. This works provides a newbus
infrastructure for device drivers wanting to use SDIO. On the lower end
while it is connected by newbus to SDHCI, it talks CAM using the MMCCAM
framework to get to it.
This also duplicates the usbdevs framework to equally create sdiodev
header files with #defines for "vendors" and "products".
