This patch fixes the problem that u-boot will not start unless icache is
enabled early.

Patch "ARM: rmobile: Mark 4-64GiB as DRAM on Gen3" marked the entire
64bit DRAM space as cachable. On CortexA57, this might result in odd
side effects, where the CPU tries to prefetch from those areas and if
there is no DRAM backing them, CPU bus hang can happen.
This patch fixes it by generating the mem_map structure based on the
actual memory layout obtained from the DT, thus not marking areas
without any DRAM behind them as cachable.

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.

Fix up the memory map on Gen3 to match datasheet properly.
This simplifies the memory map setup as well, since we do
no longer need this massive complexity.

Unify the R7A7795 and R8A7796 memory maps in memmap-gen3 and, for now,
select which one is used based on which SoC is selected. Since this is
done in C code instead of statically assigned now, the decision can be
taken by PRR SoC match as well, which will be done in a subsequent patch.

Replace the ad-hoc values in the PRR CPU ID table with macros,
so that users can use rmobile_get_cpu_type() can compare the
returned value with these macros to figure out on which CPU they
are running.
