veyron_*: Use common CBFS wrapper

This switches all the rk3288 platforms to use the common CBFS wrapper
instead of implementing its own CBFS media driver. It also happens
that veyron_* platforms use Gigadevice SPI flash (at least for now).

As we use more SPI-related stuff, for example eventlog and vboot data in
Brain's case, we will need to use more of the SPI API anyway. This
prevents us from having to duplicate pieces of it for rk3288.

BUG=none
BRANCH=none
TEST=built and booted on Pinky
