rockchip: support display

Implement VOP and eDP drivers, vop and edp clock configuration,
framebuffer allocation and display configuration logic.
The eDP driver reads panel EDID to determine panel dimensions
and the pixel clock used by the VOP.
The pixel clock is generating using the NPLL.

BUG=chrome-os-partner:31897
TEST=Booted Veyron Pinky and display normal
BRANCH=None
