Yao Zi a681cfecb4 riscv: Add a Zalrsc-only alternative for synchronization in start.S ...

Add an alternative implementation that use Zalrsc extension only for
HART lottery and SMP locking to support SMP on cores without "Zaamo"
extension available. The Zaamo implementation is still prioritized if
both of them are available, since it takes fewer instructions.
