[PATCH 2/2] riscv: Fix text patching when IPI are used

For now, we use stop_machine() to patch the text and when we use IPIs for remote icache flushes (which is emitted in patch_text_nosync()), the system hangs. So instead, make sure every cpu executes the stop_machine() patching function and emit a local icache flush there. Co-developed-by: Björn
