hw/riscv/boot.c: Introduce riscv_find_firmware()

Rename previous riscv_find_firmware() to riscv_find_bios(), and
introduce a new riscv_find_firmware() to implement the first half
part of the work done in riscv_find_and_load_firmware().

This new API is helpful for machine that wants to know the final
chosen firmware file name but does not want to load it.
