hw/riscv: spike: Decouple create_fdt() dependency to ELF loading

Browse source 
At present create_fdt() calls htif_uses_elf_symbols() to determine
whether to insert a <reg> property for the HTIF. This unfortunately
creates a hidden dependency to riscv_load_{firmware,kernel} that
create_fdt() must be called after the ELF {firmware,kernel} image
has been loaded.

Decouple such dependency be adding a new parameter to create_fdt(),
whether custom HTIF base address is used. The flag will be set if
non ELF {firmware,kernel} image is given by user.
