During SSR up, gpr-lite tries to register with audio_notifier during
gpr_probe, audio_notifier needs notifier_mutex during registration,
this mutex can also be held by audio_notifer callback. In some corner
cases, it was never getting unlocked from audio_notifier_callback,
because clk_enable/disable calls will call gpr_send_pkt, but as ADSP up
command is still not received by gpr-lite, it was returning back that
command with error code -ENETRESET. This creates a deadlock situation,
to avoid such corner cases, remove check from gpr_send_pkt. GPR clients
can ensure apm is up before sending the data.

Few Fixes on the drivers we are making are
1. snd_event is not resetting client info on deregister.
2. audio_prm is not providing the snd event up notification
3. gpr_lite reversing registration seq to avoid race condition
4. pinctrl-lpi reversing reg seq to avoid race condition.
