RISC-V: virt: This is a "sifive,test1" test finisher

Browse source 
The test finisher implements the reset command, which means it's a
"sifive,test1" device.  This is a backwards compatible change, so it's
also a "sifive,test0" device.  I copied the odd idiom for adding a
two-string compatible field from the ARM virt board.
