	Hi all,

Despite using the same compatible values ("r8a7795"-based) because of
historical reasons, R-Car H3 ES1.x (R8A77950) and R-Car H3 ES2.0+
(R8A77951) are really different SoCs, with different part numbers.

Hence this patch series splits the config symbols for R-Car H3, and
renames the related DTS files, to maintain a clear separation between
early (ES1.x) and later (ES2.0+) SoC revisions.  This will pave the way
for configuring out support for early SoC revisions, which can reduce
kernel size, especially in the pin control subsystem.
This is similar to the recent split of R8A7796 symbols for R-Car M3-W
(R8A77960) and M3-W+ (R8A77961)[1], and the related DTS file renames[2],
but different due to the sharing of compatible values between R-Car H3
ES1.x and H3 ES2.0+.

This series also includes the rename/cleanup of the ULCB DTS file names,
as suggested by Eugeniu Rosca.  As DTS files are already being renamed
for v5.6[2], it makes sense to combine them with other renames, to avoid
inconveniencing the user with multiple renames in multiple kernel
versions.

The pin control part will be handled in a separate patch.

For your convenience, all of this is available in the
topic/r8a7795-rename-v1 branch of my renesas-drivers git repository at
git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git.

Thanks for your comments!
