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.

Secure Memory Touch Arbiter is the same thing as the TrustZone
Protection Controller found on A31/A31s.
Access to many peripherals on the H3 can be controlled by the SMTA,
and the settings default to secure access only.
This patch supports the new settings, and sets them to allow non-secure
access.

On the A31s the RTC is by default secured. Thus when u-boot
loads the kernel in non-secure world, the RTC is unavailable. The
SoC has a TrustZone Protection Controller, which can be used to
enable non-secure access to the RTC.
On the A31 the TZPC doesn't seem to do anything, i.e. changes to
its register contents do not affect access to the RTC.
