This patch adds a 70ms mystery delay to the bridge driver in enable.
By experimentation, it seems like it can go anywhere up until we

This was hand-rolled in the first version, and will surely be useful as
we expand the driver to support more varied use cases.
Changes in v2:
- Change subject prefix s/panel/bridge/

prepare() is the old-timey way to say pre_enable(). It should be called
before modeset. This fixes an issue where the panel on cheza must have

Hi Sean,
Thanks for your patch.
I also made this similar change as part of my PSR support changes (yet
to be posted for review). But since this patch is posted now, i will
pick this for my PSR changes.
