we use the delay 200ms to meet the edp power timing request before,
it waste time, so we use the HPD function to detect the edp panel now.
In previous version, the hardware may not support the edp HPD function,
so in the code it will spend 200ms to detect hpd single, if it don't get
the hpd single, it will contiue the edp initialization process, to compatible
all of the hardware version.

We use the devicetree to pass the backlight control gpio before,
but if there have different board version, and it uses different
io to control backlight, it will hard to distinguish it. So, we
move the backlight control to mainboard, and use board_id
to distinguish the backlight control.

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.
