b43: Add driver load messages
This adds printk messages with basic information about the driver being loaded. This information includes a summary of the compiled-in features, which simplifies bug-reporting and debugging a lot. Also a firmware ID is printed. This is a unique identifier blob for a specific version of the firmware. This ID is attached to a specific version of the firmware blob in b43-fwcutter (see fwcutter git). This helps users to select the right firmware for their device. This also makes it possible to use automated scripts to fetch and extract the right firmware for the driver. (the script will grep the .ko for the "Firmware-ID: xxx" string. While the driver might still support other versions of the firmware for backward compatibility, this will always print out the officially supported version, which people _should_ use.
