Add /proc/boardinfo to get mainboard and BIOS info easily on the Loongson
platform, this is useful to point out the current used mainboard type and
BIOS version when there exists problems related with hardware or firmware.

Hi Tiezhu,

You're touching Kernel userspace API and I believe it should be documented. Also linux-api list
should be informed.

Also I'd like to know if it's really useful for mainline kernel.
For user who wants to check board information, dmidecode is already useful enough.

Thanks.

[loongson@linux ~]$ cat /proc/boardinfo
