Some eDP panels that are designed to be always connected to a board use their HPD signal to signal that they've finished powering on and they're ready to be talked to. However, for various reasons it's possible that the HPD signal from the panel isn't actually hooked up. In the case where the HPD isn't hooked up you can look at the timing diagram on the panel datasheet and insert a delay for the maximum amount of time that the HPD might take to come up. Let's add support in simple-panel for this concept. At the moment we will co-opt the existing "prepare" delay to keep track of the delay and we'll use a boolean to specify that a given panel should only apply the delay if the "no-hpd" property was specified.
