We'll change the aplic DT nodename in the next patch and the name is hardcoded in 2 different functions. Create a helper to change a single place later. While we're at it, in create_fdt_socket_aplic(), move 'aplic_name' inside the conditional to avoid allocating a string that won't be used when socket == NULL.
