[PATCH] riscv: Fix IPI not initialized in riscv_cpu_setup()

[Nikita Shubin]

If riscv_cpu_setup() is skipped we end up with riscv_init_ipi() not
being called.

But we still use riscv_send_ipi() in spl_invoke_opensbi(), so even if
CONFIG_PHASE_CPU not set we still need init IPI and clear pending IPIs
on harts.

Fixes: d8810e1d4f82 ("riscv: Skip riscv_cpu_setup() when CPU driver is 
disabled")
