dts: bindings: riscv: Don't use riscv, prefix for vendor compat

In 8f9290d2741844 ('dts: bindings: riscv: Add and use bindings for
sifive CPUs'), new compat strings for SiFive CPUs were added, but with
riscv prefixes. Vendor-specific compats should just be prefixed with the
vendor, so move that over here.

Fixes: 8f9290d2741844 ('dts: bindings: riscv: Add and use bindings
  for sifive CPUs')
