veyron jaq, jerry, minnie and speedy have mostly redundant regulator
and pinctrl configurations for the panel/backlight. Consolidate these
pieces in the eDP .dtsi.

Also change the default power supply for the panel to
'panel_regulator', instead of overriding it in all the board files.
pinky is the only device that uses 'vcc33_lcd' (the prior default),
so overwrite it in this case. pinky doesn't have a complete display
configuration, to keep things as they were delete the common nodes
that didn't exist previously in pinky's board file.

You forgot to remove the line:

power-supply = <&backlight_regulator>;

...from minnie.

Might as well put a space before the "="?

I general as the defender of "pinky", I'll let Heiko confirm he's OK
with the color of this bikeshed.  Sometimes a bit of repetition is
preferred over a bunch of confusing /delete-node/ statements since
those tend to make things harder to reason about in general.  In this
case I think things are cleaner after your patch but I won't say it's
100% clear cut.

Other than nits I have double-checked this patch, so feel free to add
my Reviewed-by after nits are fixed.

going this way with the delete-nodes looks good to me :-) ... pinky is
the "odd" one in that, so I think it can carry the burden ... especially
as you said, this really only affects me and my boardfarm at all ;-) .

I agree that some repetition can be preferrable over /delete-node/
statements. In this case repetition is above my personal threshold,
especially since I'm about to add another device with eDP display and
would have to repeat the mostly redundant config yet another time.

If Heiko prefer's the repetition so be it :)
