Build an SPL which can be started via SCIF download mode on R-Car Gen3
and allows loading and executing U-Boot uImage with the next stage code.
This is also useful for starting e.g. ATF BL2, which inits the hardware
and returns to the U-Boot SPL, which can then load e.g. U-Boot proper.
The H3, M3-W, M3-N SoCs have plenty of SRAM for storing the U-Boot SPL
while the payload, e.g. ATF BL2, executes, so there is no problem here.
However, E3 and D3 have much less SRAM, hence the loader uses a trick
where it copies itself beyond the area used by BL2 and executes from
there. That area is 32kiB large and not enough to hold U-Boot SPL, BSS,
stack and malloc area, so the later two are placed at +0x4000 offset
from start of SRAM, another area not used by ATF BL2. To make things
even more complicated, the SCIF loader cannot load to the upper 32kiB
of the SRAM directly, hence the copying approach.

This patch removes 'console=' argument, because kernel uses

Drop the CONFIG_MMC_RENESAS_TUNING symbol from Gen3 configs.
This symbol is no longer used after the Matsushita SDHI driver,
instead the renesas-sdhi driver uses CONFIG_MMC_HS200_SUPPORT
to discern whether the tuning support should be compiled in.

Enable the HS200 on RCar Gen3 platforms, since the SDHI core supports it.

Since the Renesas SDHI has it's own custom driver sharing the
common code with Uniphier one, adjust the Kconfig entries.

Enable support for applying DT overlays on Gen3. This is convenient
for handling extra additional hardware, like ie. the Kingfisher.

On the NIOS2 and Xtensa architectures, we do not have
CONFIG_SYS_TEXT_BASE set. This is a strict migration of the current
values into the defconfig and removing them from the headers.
I did not attempt to add more default values in and for now will leave
that to maintainers.

Pull out u-boot extras into dtsi files to make synchronization of DTS
from Linux kernel as easy as a simple copy. All the U-Boot extras are
now in *-u-boot.dts* files instead.
