Attempt to cope with the dev/rmi -> mips/rmi/dev move.

Merge from projects/mips to head by hand:

Copy sys/dev/rmi to sys/mips/rmi/dev [sic]. For devices that are on
only one SoC, or family of SoC, we place them under sys/<vendor>/dev.
I'll fix the build problems this causes as best I can since rmi kernel
require external toolchains due to lack of support for rmi op-codes in
the ancient binutils we have in the tree.

white space changes

Adds the untouched code from the RMI 6.4 stuff.
This has a security device and the gig ethernet device.
Note the 10gig device driver is yet missing.
