Sean Anderson 768502e2a7 riscv: Clear pending IPIs on initialization ... Even though we no longer call smp_function if an IPI was not sent by U-Boot, we still need to clear any IPIs which were pending from the execution environment. Otherwise, secondary harts will busy-wait in secondary_hart_loop, instead of relaxing. Along with the previous commit ("riscv: Use a valid bit to ignore already-pending IPIs"), this fixes SMP booting on the Kendryte K210.
