riscv: Small fix to CPU compatibility identification

Browse Source 
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.
