Do we even need HVC_SBI console to be enabled by default? Disabling CONFIG_HVC_RISCV_SBI seems to be fine while running in QEMU.

If we don't need it, I suggest we should remove the config option from defconfig in addition to this patch.

I think the whole concept of the SBI console is a little dangerous. It means that for one piece of physical hardware (usually the uart) we have two entiries (the M-mode firmware and the OS) in control, which tends to rarely end well.
