rockchip: Rename jerry files to veyron

At present we have a single rk3288-based Chromebook: chromebook_jerry. But
all such Chromebooks can use the same binary with only device-tree
differences. The family name is 'veyron', so rename the files accordingly.

Also update the device-tree filename since this currently differs from
Linux.
