[PATCHv3] coresight: etm4x: Fix etm4_count race by moving cpuhp callbacks to init

etm4_count keeps track of number of ETMv4 registered and on some systems, a race is observed on etm4_count variable which can lead to multiple calls to cpuhp_setup_state_nocalls_cpuslocked(). This function internally calls cpuhp_store_callbacks() which prevents multiple registrations of callbacks f

Hi Linus, I'm sending this out a bit early, just to give you a chance to reject it or help decide on an rc8. The nouveau fixes missed the last pull by a few hours, and we had a few arm driver/panel/bridge fixes come in. This is possibly a bit more than I'm comfortable sending at this stage, but I
