test: Make a copy of the device tree before running a test

When the flat device tree changes it can mess up the live tree since that
uses the flat tree for its strings. This affects only a few sandbox tests
which modify the device tree, but the number will grow as ofnode support
for writing improves.

While the control FDT is not intended to change while U-Boot is running,
some tests do so. For example, the ofnode interface only supports
modifying properties in the control FDT, so tests must use that.

To solve this problem, keep a copy of the FDT and restore it as needed
when the test is finished. The copy only happens on sandbox (except SPL
builds), to reduce memory usage and because these tests are not useful on
other boards. For other boards, a checksum is taken to ensure that nothing
changes.

It would be possible to always checksum the FDT on sandbox and only
restore it if needed, but this is slightly slower than restoring it every
time, at least with crc8.

Merge branch '2022-09-23-4gb-ddr-in-32bit-ppc' into next

To quote the author, for the first 9 patches:
This patch series fixes U-Boot code to correctly handle RAM size larger
than 2 GB and then fixes fsl ddr driver to do not crash U-Boot when 4 GB
DDR module is detected when U-Boot operates in 32-bit mode (as opposite
of the 36-bit mode).

With this patch series it is possible to boot 32-bit U-Boot with 4 GB
SODIMM DDR3 module without crashes. U-Boot will still use just
CONFIG_MAX_MEM_MAPPED amount of RAM, but it is better than crashing due
to the truncating of 4GB value to 32-bit number (which is zero).

I tested this patch series on powerpc P2020 based board but only with
U-Boot v2022.04 because U-Boot master branch is still broken on P2020.

And then the final two patches here are (in my mind at least) related
clean-ups.

board_f: show_dram_config: Print also real DRAM size

32-bit U-Boot builds cannot use more than around 2 GB of DDR memory. But on
some platforms/boards it is possible to connect also 4 GB SODIMM DDR memory.
U-Boot currently prints only effective size of RAM which can use, which may
be misleading as somebody would expect that this line prints total size of
connected DDR modules. So change show_dram_config code to prints both real
and effective DRAM size if they are different. If they are same then print
just one number like before. It is possible that effective size is just few
bytes smaller than the real size, so print both numbers only in case
function print_size() prints formats them differently.
