At present of-platdata does not provide parent information. But this is
useful for I2C devices, for example, since it allows them to determine
which bus they are on.

Add support for setting the parent correctly, by storing the parent
driver_info index in dtoc and reading this in lists_bind_drivers(). This
needs multiple passes since we must process children after their parents
already have been bound.

At present MKIMAGE_DTC_PATH is in the devicetree menu but not within
'devicetree control' since it does not relate to that. As a result it
shows up in the top menu.

It actually relates to the mkimage tool, so create a new tools menu for it
and move it there.

This can be used for device tree size reduction similar as
CONFIG_OF_SPL_REMOVE_PROPS option. Some boards must pass the
built-in DTB unchanged to the kernel, thus we may not cut it
down unconditionally. Therefore enable the property removal
list option only if CONFIG_OF_DTB_PROPS_REMOVE is selected.

Some features implicitly depended on MALLOC_F and OF_LIBFDT and would
fail at link-time if these features were not enabled.

If u-boot.img is a FIT image, CONFIG_OF_OVERLAY_LIST can be used to add
DT overlays to u-boot.img.

This choice is not about SPL for which we have a separate choice.

As initially this feature was implemented as a negative CONFIG and
later it was redesigned to be positive the help text should be
updated to reflect this change.

This commit updates the help text to match the current implementation.

interrupt-parent property is removed already that's why there is no
reason to keep interrupts property if parent doesn't exist.

Add required Kconfig symbols, Makefile bits and macro fixes in a
few places to support LZO and DT compression in U-Boot. This can
save a lot of space with multi-DTB fitImages.

This reverts commit 27cb7300ffda7a3f1581f0f5a2d3bfe59b97ad67.

I am not sure if I correctly understood the log of commit 27cb7300ffda
("Ensure device tree DTS is compiled"), but the code-diff looks like
it was trying to solve the missed re-compilation when .dts was modified.

Recently, commit 2737dfe096b6 ("kbuild: make arch-dtbs target PHONY")
fixed the issue in a more correct and more complete way.

Anyway, since the former commit, we see a clumsy log like this:

  make[2]: 'arch/sandbox/dts/sandbox.dtb' is up to date

Another problem is, it created multiple paths to descend into
arch/*/dts/, causing a race in parallel building.

So, let's revert it.
