Alper Nebi Yasak a355ece8e6 video: rockchip: Restrict EDP, VOP, MIPI files to GPL-2.0
These files have a lot of code in common with their counterparts in
coreboot, especially in their earlier revisions:

Restrict the licenses to match coreboot's so that changes from coreboot
can be imported to U-Boot as necessary. HDMI files are already 2.0+
there and rk_lvds.c has no counterpart, so keep them as is.
