MIPS: DEC: Add R4k DECstation defconfig

This supports computers based on the R4000SC processor:

* DECstation 5000/150 and DECsystem 5000/150,

* Personal DECstation 5000/50, Personal DECsystem 5000/50,

and computers based on the R4400SC processor:

* DECstation 5000/260 and DECsystem 5000/260,

* DECsystem 5900/260,

in the 32-bit mode.
