msm: qpnp-haptic: Process haptics asynchronously
Blocking the timed_output sysfs node due to mutex contention causes severe
device wake-up latency, as a process crucial to system resume writes to the
timed_output vibrator node every time the device is resumed via the
fingerprint reader (fingerprint reader triggers a haptic response on
success).
By processing haptics asynchronously via a worker, the timed_output sysfs
won't get stalled for long periods of time (>30ms), and thus the device
will consistently wake from sleep faster.
