Subject: [PATCH 4/5] ARM: dts: rockchip: vcc33_ccd off in suspend for rk3288-veyron-chromebook

As per my comments when the device tree for rk3288-veyron-chromebook
first landed:

> Technically I think vcc33_ccd can be off since we have
> 'needs-reset-on-resume' down in the EHCI port (this regulator is for
> the USB webcam that's connected to the EHCI port).
>
>  ...but leaving it on for now seems fine until we get suspend/resume
> more solid.

It's probably about time to do it right.
