The RK3288 SoC is a low power, high performance processor for mobile phones,
personal mobile internet devices and other digital multimedia applications.
It has an integrated quad-core cortex-A17 with separate NEON coprocessor.
Prepare mach-rockchip infrastructure for Rockchip RK3288 support.
Let's seperate the RK3188 and RK3288 SoCs. Later we will have two different
configs.
