[PATCH 2/2] riscv: Enable generic clockevent broadcast

From: Guo Ren When percpu-timers are stopped by deep power saving mode, we need system timer help to broadcast IPI_TIMER. This is first introduced by broken x86 hardware, where the local apic timer stops in C3 state. But many other architectures(powerpc, mips, arm, hexagon, openrisc, sh) have
