This reverts commit c7e4a2a72e696aa6aed2c8b651279f491bb096fe.
The patch causes sc7180 Chromebooks that use the parade-ps8640 bridge chip to fail to turn the display back on after it turns off.
Let's revert to get these devices back to a working state. It seems like the DSI powerup problem is somewhat common and probably we should land something more general like Dave Stevenson's series [1] that would give more flexibility.

Well, that's embarrassing. I clearly reverted the wrong copy of this patch. Sorry. v2 coming right up.
