The supervisor binary interface (SBI) provides the necessary functions to implement the platform IPI functions riscv_send_ipi() and riscv_clear_ipi(). Use it to implement them. This adds support for inter-processor interrupts (IPIs) on RISC-V CPUs running in supervisor mode. Support for machine mode is already available for CPUs that include the SiFive CLINT.
