riscv: kernel: add console driver for S-Mode using SBI
Implements a generic console driver using legacy SBI extension.
This introduces a flag CFG_RISCV_SBI_CONSOLE to decide building
the driver or not. This allows using another UART driver instead.

core: riscv: plat-spike: console driver based on host-target interface
Spike doesn't yet model a UART but relies on RISC-V Host-Target Interface
(HTIF) to perform all I/O. It is a protocol allowing the target to access
host to perform console, storage etc. It requires special ELF symbols
tohost and fromhost. HTIF base address is set to 0x40008000.
