So far we stated the lack of a lowlevel() init function for the
Allwinner F1C100s board by defining the respective SKIP_* symbol in the
board's defconfig. However we don't expect any *board* to employ such
low level code, so expect this to be never used for the ARMv5 Allwinner
SoCs.
Select the appropriate symbols in the Kconfig, so that we can remove
them from the defconfig, and avoid putting them in future defconfigs for
other boards.

As the compile error when D-Cache is enabled is gone, we can have
D-Cache enabled now.

When some configuration symbols were converted from header files to
Kconfig, their values were placed into *every* defconfig file.
Since we now have sensible per-SoC defaults defined in Kconfig, those
values are now redundant, and can just be removed.
This affects CONFIG_SPL_STACK, CONFIG_SYS_PBSIZE, CONFIG_SPL_MAX_SIZE,
and CONFIG_SYS_BOOTM_LEN.

Many LicheePi Nano boards come with SPI flash soldered, which already
works for booting the SPL and loading U-Boot proper.
With the updated DTB, we can now also use the SPI flash from U-Boot
proper, so enable the bits in the defconfig, to allow loading binaries
from SPI flash.
There seem to be board revisions with a Winbond SPI chip, but also
others with an XTX chip, so include support for both: the actual chip
used will be autodetected.

The original Allwinner F1C100 .dtsi imported from the Linux kernel tree
used the wrong compatible string for the watchdog timer, so the Allwinner
DM reset driver was not working properly. We worked around this by
disabling the SYSRESET driver, so the hardcoded SPL reset driver took
over.
Now the issue was fixed in the DTs in mainline Linux, and we synced the
fixed .dtsi file into U-Boot, so drop the hack and use the normal U-Boot
proper reset infrastructure.
This reverts commit cfcf1952c1.

The F1C100s DT contains the wrong compatible string for the watchdog,
which breaks reset functionality.
Updating the DT goes via the Linux tree, but to allow reset
functionality meanwhile (useful for development!), disable SYSRESET for
now, to let the old-fashioned watchdog driver kick in and provide the
reset_cpu() implementation.
