When OF_LIVE flag is enabled on a 64 bits platform, there is an
issue when dev_read_addr() is called and need to perform an address
translation using __of_translate_address().

In case of error, __of_translate_address() return's value is OF_BAD_ADDR
(wich is defined in include/dm/of.h to ((u64)-1) = 0xffffffffffffffff).
The return value of dev_read_addr() is often compared to FDT_ADDR_T_NONE
which is defined as (-1U) = 0xffffffff.
In this case the comparison is always false.

To fix this issue, define FDT_ADDR_T_NONE to (ulong)(-1) in case of
AARCH64. Update accordingly related tests.

Sphinx expects Return: and not @return to indicate a return value.

This old macro is not needed anymore since we can use IS_ENABLED() now.
Drop it.

Keep track of where the devicetree came from, so we can report this later.

At present this override function is called even when OF_BOARD is not
enabled. This makes it impossible to disable this feature and in fact
makes the OF_BOARD option useless.

Reinstate its intended purpose, so that it is possible to switch between
the appended devicetree and one provided by the board's custom function.

A follower patch adds warnings for this scenario, but for now we don't
have a Kconfig that definitively tells us that OF_BOARD should be used.

Move this to the header file to clean up the C code.

OF_HOSTFILE is used on sandbox configs only.  Although it's pretty
unique and not causing any confusions,  we are better of having simpler
config options for the DTB.

So let's replace that with the existing OF_BOARD.  U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

The previous patches removed OF_PRIOR_STAGE from the last consumers of the
Kconfig option.  Cleanup any references to it in documentation,  code and
configuration options.

Reserved memory nodes can have additional flags. Support reading and
writing these flags to ensure that reserved memory nodes can be properly
parsed and emitted.

This converts support for the existing "no-map" flag to avoid extending
the argument list for fdtdec_add_reserved_memory() to excessive length.
