Subject: [PATCH 2/3] tty: riscv: Using RISCV_SBI_V01 instead of RISCV_SBI

As shown in SBI v0.2, the legacy console SBI functions (sbi_console_getchar()
and sbi_console_putchar()) are expected to be deprecated; they have no replacement.

Let's HVC_RISCV_SBI and SERIAL_EARLYCON_RISCV_SBI depends on RISCV_SBI_V01.

Fixes: efca13989250 ("RISC-V: Introduce a new config for SBI v0.1")
