We don't have any uses of this form of define so deprecate it for now.
If needed this should be DT_INST_<INSTANCE ID>_<COMPAT>_BUS_<BUS>.

Discovered with pylint3.
Use the placeholder name '_' for unproblematic unused variables. It's
what I'm used to, and pylint knows not to flag it.
Also improve the naming a bit in devicetree.py. If a key/value is known
to be a specific thing (like a node), then it's helpful to call it that
instead of something generic like "value".

It's confusing that "address" is often used within the same function to
refer to both node paths and e.g. address cells.
Make things easier to understand by calling /foo/bar a path instead.

Less spammy and as easy to understand ("label" seems a bit confusing
though, but it's consistent with other code).
Also simplify some surrounding code, and clean up the implementation of
str_to_label() a bit.

Pass the dictionary of definitions directly. Shorter and clearer.
Also get rid of some other temporary variables, a redundant str() call,
and some mysterious commented-out code in _extract_flash().

Add support to generate defines of the form
DT_<COMPAT>_<INSTANCE>_<PROP>. The idea is that we can utilize this in
drivers to remove the need for dts_fixup.h. The <INSTANCE> value is
determined by the script and starts at 0 and counts up for each instance
of a given <COMPAT>.

For devices on buses like I2C or SPI its possible that a sensor might
support being on either bus type. In the dts we can tell this by
looking at the parent bus of the device. Its useful for a driver to
know this so can we build support into the driver accordingly.
For example if the LSM6DSL sensor ("st,lsm6dsl") is in the dts on a spi
bus we now generate:
#define DT_ST_LPS22HB_PRESS_BUS_SPI 1
Its possible that a system exists in which multiple of the same sensor
exist but on different busses, so drivers should handle that case
accordingly. For the LSM6DSL example we'd end up with:
#define DT_ST_LPS22HB_PRESS_BUS_I2C 1
#define DT_ST_LPS22HB_PRESS_BUS_SPI 1

Various functions like add_prop_aliases, extract_single_prop,
extract_single, reg.extract, compatible.extract, default.extract, and
flash.extract don't use the yaml argument that is passed to them.
Remove passing the argument, this is the first step in making access to
the yaml node information go through an accessor function.

Compat define is generated without value. This should not harm,
but since generated flag is a "Kconfig like" define, we migth need it
to hold a value.

Parameter 'names' is provided as argument of several property
extract functions. Thought it is actually used only once.
Remove when not needed.

Generate CONFIG_DT_COMPAT flags using available nodes
'compatible' property.
Store them in a bogus node_address key of defs dict so
duplicates could be removed.
