Add support for the R-Car S4 Starter Kit with R8A779F4 SoC support.
This implementation natively uses OF_UPSTREAM to pull in most recent
DT. The defconfig is derived from S4 Spider, with reduced UART baud
rate to 921600 Bdps. The DT alias to rswitch is removed as the alias
should point to rswitch ports, not to rswitch itself, see [1].

Deduplicate defconfigs for all Renesas R-Car Gen4 systems by factoring
out the common parts into generic renesas_rcar4.config and including
those using the #include <configs/...> preprocessor macro in the current
set of board specific defconfigs. The preprocessor macro is applicable
to defconfigs as well.
This introduces no functional change, the resulting .config is identical
for all Renesas R-Car Gen4 systems.

Switch PHY_ANEG_TIMEOUT to CONFIG_PHY_ANEG_TIMEOUT Kconfig symbol.
This removes one more configuration headers option finalizes its
Kconfig symbol conversion. No functional change expected.

Enable OF_UPSTREAM to use upstream DT and add renesas/ prefix to the
DEFAULT_DEVICE_TREE and OF_LIST. And thereby directly build DTB from
dts/upstream/src/ including *-u-boot.dtsi files from arch/$(ARCH)/dts/
directory.
The configuration update has been done using the following script:
```
sed -i '/^CONFIG_DEFAULT_DEVICE_TREE/ s@="@&renesas/@' `git grep -li renesas configs`
sed -i '/^CONFIG_OF_LIST/ s@r8a@renesas/&@g' `git grep -li renesas configs`
```
There are SoCs which are not included in this patch. The 32bit SoCs
require further infrastructure work. R8A779H0 is coming during the
next upstream DT synchronization cycle as it is not included in
current upstream DTs yet.

The U-Boot build system can automatically paste -u-boot.dtsi at the
end of matching .dts during build. Stop emulating this behavior and
rename the -u-boot.dts files to -u-boot.dtsi, drop "#include...dts"
from those new u-boot.dtsi files, and update board configuration
accordingly.
The rename, '#include...dts` scrubbing and configuration update has
been done using the following script:
```
$ find . -name r[78]\*-u-boot.dts | sort -u | while read line ; do \
git mv ${line%-u-boot.dts}-u-boot.dts ${line%-u-boot.dts}-u-boot.dtsi ; \
done
$ sed -i '/^#include.*dts"/ d' `find . -name r[78]\*-u-boot.dtsi`
$ sed -i 's@-u-boot@@g' `git grep -li renesas configs`
```
The Salvator-X and ULCB board files have been updated manually.

Marek Vasut <marek.vasut+renesas@mailbox.org> says:
Rename R-Mobile to Renesas all over the place because the chips are
made by Renesas, while only a subset of them is from the R-Mobile line.
Rename ARCH_RMOBILE to ARCH_RENESAS because all the chips are made
by Renesas, while only a subset of them is from the R-Mobile
line.
Use the following command to perform the rename:
"
$ git grep -l 'ARCH_RMOBILE' | xargs -I {} sed -i 's@ARCH_RMOBILE@ARCH_RENESAS@g' {}
"

Enable UFS controller driver and matching UFS and SCSI commands. The
former is used to initialize the device, the later is used to perform
low level access to the SCSI interface of the UFS device.
Enable R8A779F0 S4 Spider specific dependencies, the PCA953x driver
and GPIO clock gate driver. This setup is used to toggle 38.4 MHz
clock for the UFS controller.
Enable support for 48bit LBA in block layer to address disks larger
than 512*2^32 ~= 144 PiB. Enable use of 64bit LBA variables in the
rest of U-Boot, instead of the default 32bit ones.
Increase FAT cluster size to 128k as that is what is used by the
filesystem that is populated on the UFS device.
Use 'ufs init && scsi scan' to start the UFS device from U-Boot prompt.

Mallocate gd->bd->bi_boot_params, i.e. drop the assignment
Sort headers, use clrbits_le32(), use BIT macros where appropriate
