uboot code is setting it to 1. Change the configuration to match the
linux configuration

04d67ceb1c rockchip: video: edp: Add rk3399 support
According to linux commit "drm/rockchip: analogix_dp: add rk3399 eDP
support" (82872e42bb1501dd9e60ca430f4bae45a469aa64), rk3288 and rk3399
eDP IPs are nearly the same, the difference is in the grf register
(SOC_CON6 versus SOC_CON20). So, change the code to use the right
register on each IP.

The clocks don't seem to be the same, the eDP clock is not at index 1
on rk3399, so don't try changing the clock at index 1 to rate 0 on
rk3399.

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.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

Some Rockchip SoCs support embedded DisplayPort output. Add a display driver
for this so that these displays can be used on supported boards.
