Add generation of the following macros:
DT_N_<node-id>_REG_IDX_<idx>_EXISTS 1
DT_N_<node-id>_IRQ_IDX_<idx>_EXISTS 1
This will allow us to use IS_ENABLED() in DT_REG_HAS_IDX and
DT_IRQ_HAS_IDX which matches behavior of other DT_*_HAS_* macros as
well as lets use these with COND_CODE_1.

Add generation of the following macros:
DT_N_<node-id>_P_<prop-id>_NAME_<NAME>_EXISTS
DT_N_<node-id>_P_<prop-id>_IDX_<idx>_EXISTS
This will be useful to check availability of named or indexed
property like dmas/dma-names.

Zephyr board names must be globally unique which requires that they
encode all necessary information to identify a specific target.
Typing in these names can be inconvenient to developers working on
multiple targets within a single workspace.
Extend the cmake infrastructure to read an optional board aliases file
that will map custom aliases to the corresponding canonical Zephyr
board name.

Due to the use of UTIL_EVAL*() macros, the UTIL_LISTIFY() macro used
by DT_INST_FOREACH(foo) can cause long build errors when there is a
build error in the expansion for "foo". More than a thousand lines of
build error output have been observed for an error in a single line of
faulty C.
To improve the situation, re-work the implementation details so the
errors are a bit shorter and easier to read. The use of COND_CODE_1
still makes the error messages quite long, due to GCC generating notes
for various intermediate expansions (__DEBRACKET,
__GET_ARG_2_DEBRACKET, __COND_CODE, Z_COND_CODE_1, COND_CODE1), but
it's better than the long list of UTIL_EVAL notes.

Now that the west parts of this file are in better shape, it seems a
shame not to flesh out the rest a bit more.
It's been a while since we looked at this document, as it's still
referring to boards (like Arduino 101) that are no longer supported by
Zephyr, and is generally lacking in concrete, step-by-step advice
for going from zero to working board.
Let's fix that.

The "fixed-clock" value referenced in the documentation is actually a
compatible value, not a property name. Fix that.
Harden the "expected to have a clock-frequency property" language to
use "must" instead of "expected". The scripts error out if a node with
fixed-clock compatible is missing a clock-frequency property; it's not
a soft expectation.
Be explicit about clock-frequency units.
