hw/char: riscv_htif: Support console output via proxy syscall
At present the HTIF proxy syscall is unsupported. On RV32, only
device 0 is supported so there is no console device for RV32.
The only way to implement console funtionality on RV32 is to
support the SYS_WRITE syscall.
With this commit, the Spike machine is able to boot the 32-bit
OpenSBI generic image.
