riscv: start to use the configstring functions
These functions will allow us to remove hardcodes, as long as we can verify the qemu and lowrisc targets implement the configstring correctly. Hence, for the most part, we'll start with mainboard changes first. Define a new config variable, CONFIG_RISCV_CONFIGSTRING, which has a default value that works on all existing systems but which can be changed as needed for a new SOC or mainboard.
