Any user of wkup_m3_ipc calls wkup_m3_ipc_get to get a handle and this checks the value of the static variable m3_ipc_state to see if the wkup_m3 is ready. Currently this is populated during probe before rproc_boot has been called, meaning there is a window of time that wkup_m3_ipc_get can return a valid handle but the wkup_m3 itself is not ready, leading to invalid IPC calls to the wkup_m3 and system instability. To avoid this, move the population of the m3_ipc_state variable until after rproc_boot has succeeded to guarantee a valid and usable handle is always returned.
