mhi_power_down() does not ensure that the PM state is moved to an inaccessible state soon enough as the system can encounter scheduling delays till mhi_pm_disable_transition() gets called. Additionally, if an MHI controller decides that the device is now inaccessible and issues a power down, the register inaccessible state is not maintained by moving from MHI_PM_LD_ERR_FATAL_DETECT to MHI_PM_SHUTDOWN_PROCESS. This can result in bus errors if a client driver attempted to read registers when powering down. Close these gaps and avoid any race conditions to prevent such activity.
