Re: [PATCH v7 15/22] riscv: Clean up IPI initialization code

The previous IPI code initialized the device whenever the first call was made to a riscv_*_ipi function. This made it difficult to determine when the IPI device was initialized. This patch introduces a new function riscv_init_ipi. It is called once during arch_cpu_init_dm. Before this point, no riscv_*_ipi functions should be called.
