veyron: Rename "veyron" board to "veyron_pinky"

We retroactively decided to use the variant name "pinky" for the Rk3288
board we're currently bringing up, and retcon the unadorned "veyron"
name to refer to the Rockchip evaluation board. Since we currently have
no interest to maintain coreboot support for that board in our tree,
let's rename everything to "veyron_pinky" and forget about "veyron".

CQ-DEPEND=CL:217592
BUG=chrome-os-partner:30167
TEST='emerge-veyron libpayload coreboot' fails but
'emerge-veyron_pinky libpayload coreboot' succeeds.
