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.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

lcdif_power_down() assumes that the LCDIF controller has been properly
configured and enabled, which may not be true.

To fix this issue check whether panel.frameAdrs has been initialized and
in case it has not been initialized, do not continue with the LCDIF
powerdown sequence.

Tested on a imx7dsabresd board.

video: mxsfb: introduce lcdif_power_down

Introudce a new function lcdif_power_down.

1. Waits for a VSYNC interrupt to guarantee the reset is done at the
VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?)
and helps the LCDIF work normally at the kernel stage.
2. Add power down function to stop lcdif.

The reason to introduce lcdif_power_down is that we want lcdif to be in
initial state when doing uboot reset or before kernel boot to make
system stable, otherwise system may hang.
