RISC-V: virt: riscvemu: add HTIF DEBUG_LL support
Default console of riscvemu is available Virt I/O console and as a HTIF
blocking character device. We already support Virt I/O console, but the
HTIF is easier to support for very early low level debugging. Add
DEBUG_LL support to facilitate using it.
Note: when using a framebuffer, riscvemu doesn't allocate a default
console, so barebox calling into HTIF will segfault the emulator.
