[Tom Rini]

This function should now be a EVENT_SPY_SIMPLE call, update it.

[PATCH 2/2] riscv: Correct event usage for riscv_cpu_probe/setup

[Tom Rini]

With having both an EVENT_SPY_SIMPLE setup for both riscv_cpu_probe and
riscv_cpu_setup we do not need the latter function to call the former
function as it will already have been done in time.

Fixes: 1c55d62fb9cc ("riscv: cpu: make riscv_cpu_probe to EVT_DM_POST_INIT_R callback")

I cannot seem to find macro "EVENT_SPY_SIMPLE".
Is there anything that should be added?
Or did I miss anything?

This patch is only applicable to origin/next. The definition there is in 
include/event.h:311.
