riscv-trap-handling: Add implementation for trap calls in riscv
RISCV requires the bios/bootloader to set up an interface by which it
can get information about memory, talk to host devices, etc. Put
implementation for spike in
src/mainboard/emulation/spike-riscv/spike_util.c, and
src/arch/riscv/trap_handler.c
