At present there is a hex value SPL_STACK which both determines whether
SPL has its own initial stack and the hex value of that stack.

Split off the former into SPL_HAVE_INIT_STACK with SPL_STACK depending
on that and only providing the latter.

[trini: Resync defconfig files]

It seems that every remaining system which enables BITBANGMII also
enables BITBANGMII_MULTI . Remove the BITBANGMII_MULTI symbol and
assume it is always enabled. This allows removal of a bit of legacy
code. No functional change intended.

Deduplicate defconfigs for all Renesas R-Car Gen2 systems by factoring
out the common parts into generic renesas_rcar2.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 Gen2 systems.

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`
```

The RZN1 Snarc board does not seem to have a matching Linux kernel
DT counterpart, this is currently not switched to OF upstream.

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.

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' {}

These systems are unlikely to use EFI as this functionality has not been
enabled until it got pulled in by Kconfig default. This functionality
does add some 60-70 kiB to the u-boot.img size, which overflows the size
limit. Disable it.
