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.
