Log:
  riscv: Small fix to CPU compatibility identification
  
  fdt_is_compatible_strict() inspects the first compatible property.
  We need to inspect the following properties for 'riscv'.
  ofw_bus_node_is_compatible() does a recursive search.
  
  This patch fixes "Can't find CPU" error message when bootverbose = true.
