rockchip/rk3288: add support for hdmi display
this is an brief hdmi driver which config with simple display parameter, const encoder input & output color format and 8bit color depth, and only 48KHz audio support. what's more to prevent TV have not show an right things before coreboot switch to kernel space, we have to add an terrible 2s delay to driver (2s come from test many times), cause we have to wait TV to respond (we got no flag to check whether it is ready).
