Rick Chen e0465f80bd riscv: Introduce AVAILABLE_HARTS ... In SMP all harts will register themself in available_hart during start up. Then main hart will send IPI to other harts according to this variables. But this mechanism may not guarantee that all other harts can jump to next stage. When main hart is sending IPI to other hart according to available_harts, but other harts maybe still not finish the registration. Then the SMP booting will miss some harts finally. So let it become an option and it will be enabled by default.
