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