Some SPL loaders (like Allwinner's boot0, and Broadcom's boot0)
require a header before the actual U-Boot binary to both check its
validity and to find other data to load. Sometimes this header may
only be a few bytes of information, and sometimes this might simply
be space that needs to be reserved for a post-processing tool.
Introduce a config option to allow assembler preprocessor commands
to be inserted into the code at the appropriate location; typical
assembler preprocessor commands might be:
.space 1000
.word 0x12345678

Commit Notes:
Please note that the current code:
start.S (arm64) and
vectors.S (arm)
already jumps over some portion of data already, so this option basically
just increases the size of this region (and the resulting binary).
For use with Allwinner's boot0 blob there is a tool called boot0img[1],
which fills the header to allow booting A64 based boards.
For the Pine64 we need a 1536 byte header (including the branch
instruction) at the moment, so we add this to the defconfig.

Recently a set of CONFIG_CMD_FOO defines was moved from being defined
in config_distro_defaults to Kconfig, and added to all sunxi defconfigs
to compensate.
Instead of explictly selecting these in all sunxi defconfigs,
simply always select these for sunxi boards. This makes the defconfigs
simpler and ensures a consistent set of available commands across all
sunxi boards.

The originally committed .dts files for the Pine64 were from an early
proof-of-concept version and should have never been committed upstream.
Replace them with much more mature versions, which also use a different
naming scheme.
Please note that at this point there is at least one binding which has
not been agreed upon, so this is subject to change.

This syncs up the current cmd/Kconfig and include/configs/ files with the
only exception being CMD_NAND. Due to how we have used this historically
we need to take further care here when converting.

Move all cases of CONFIG_SYS_HUSH_PARSER out of the config.h files. Remove
all cases of CONFIG_SYS_PROMPT_HUSH_PS2 as everyone uses the default.

We have CONFIG_CMD_GPIO=y in almost all sunxi boards, but after
its Kconfig conversion it has ended up missing on some recently
added boards.
Simply select it for ARCH_SUNXI, so that we get it on all
sunxi boards for both a consistent user experience and simpler
defconfig files.

The Pine64+ is a system based on the Allwinner A64 SoC. It is capable of
running AArch64 code and thus is the first of its kind for the sunxi target.
This patch adds a defconfig and device tree chunks for it.
