[RFC PATCH v2 3/9] drm/panel: nv3052c: Sleep for 150ms after reset

[John Watts]

The current code waits after resets for 5 to 20 milliseconds.
This is appropriate when resetting a sleeping panel, but an awake panel
requires at least 120ms of waiting.

Sleep for 150ms so the panel always completes it reset properly.
