Like the timer of Sophgo sg2042 clint. The machine-level software
interrupt device (mswi) of sg2042 clint have the same problem when
dealing with the standard sifive clint.

To avoid the same conficts as the timer of sg2042 clint, also add the
vendor specific compatible string to identify the mswi of sg2042 clint.
