rockchip: rk3399: initialize display for eDP

This patch adds functions to init the display. To set up the display,
    initialize the eDP and read the EDID.  Based on these, we then
    set the clock for VOP, and finally enable VOP and backlight.

For a mainboard, it should set the vop_id, vop_mode and
    framebuffer_bits_per_pixel in devicetree.cb.

For VOP_MODE_AUTO_DETECT, it will try eDP first and then
    HDMI (which is not supported yet).

EDIT: Updated Makefile to only build in new files if
    MAINBOARD_DO_NATIVE_VGA_INIT is enabled. All of these
    platforms should have it enabled, so this shouldn't make
    any difference except now, before the platform code is
    in place.
