clocksource/drivers/riscv: Events are stopped during CPU suspend
[ Upstream commit232ccac1bd
] Some implementations of the SBI time extension depend on hart-local state (for example, CSRs) that are lost or hardware that is powered down when a CPU is suspended. To be safe, the clockevents driver cannot assume that timer IRQs will be received during CPU suspend. Fixes:62b0194368
