-Handle the HID driver power asynchronously to allow the IMU data be received and processed before driver acknowledge. This stage allows to mitigate the initial 3-4 seconds delay to <300msec.
The HID power management requests will be handled by FIFO queue to ensure power state state machine.
The drawback is that power change requests will be queued for execution, and in case of the very first power off request is received immediately after power on (e.g on/off stress test), it will be postponed by the same 3-4 seconds.
-Revert and remove PREVENT_HID_SUSPEND CMake option introduced in v2.17.1
