When we remove power from a device we need to let the device fully discharge and get to a quiescent state before applying power again. If we power a device on too soon then it might not have fully powered off and might be in a weird in-between / invalid state. eDP panels typically have a time that's at least 500 ms here. You can see that in Linux's panel-edp driver nearly every device specifies a "unprepare" time of at least 500 ms. This is a common minimum and the 500 ms is even in the example in the eDP spec. In Linux, the "panel-edp" driver enforces this delay for its own control of the regulator, but the "panel-edp" driver can't do anything about other control of the regulator (for instance, by the touchpanel driver). Let's add 500 ms as a board constraint for the regulator that's used for eDP/touchpanel on trogdor boards. If a given trogdor board stuffs only panels that can use a shorter time or stuff some panels that need a larger time then they can manually adjust this timing. We'll only do this minimum delay for trogdor devices with eDP (ones that use either bridge chip), not for devices with MIPI panels. MIPI panels could have similar constraints but the 500 ms isn't necessarily as standard and there are no known cases where this delay is needed. For most trogdor boards, this doesn't actually seem to affect anything when testing against shipping Linux. However, with pazqel360 it seems that this does make a difference. It seems that the touchscreen on this board _also_ needs some time for the regulator to discharge. That time is much less than 500 ms, so we'll just put the eDP panel 500 ms in there since the board constraint should be the "max" of the components.

I saw about 200 ms of delay. Let's avoid that delay by starting the regulator on. We'll only do this for eDP devices for the time being. NOTE: we _won't_ do this for homestar. Homestar's panel really likes to be power cycled. It's why the Linux driver for this panel has a pm_runtime_put_sync_suspend() when the panel is being unprepared but the normal panel-edp driver doesn't. It's also why this hardware has a separate power rail for eDP vs. touchscreen, unlike all the other trogdor boards. We won't start homestar's regulator on. While this could mean a slight delay on homestar, it is probably a _correct_ delay. The bootloader might have left the regulator on (it does so in dev and recovery modes), so if we turned the regulator off at probe time and we actually hit the delay then we were probably violating T12 in the panel spec.
