79765b8ad7 scripts/dts: fix support for uint8-array property values
uint8-array is the name for what the devicetree specification calls a
bytestring.

The original parsing code treated square brackets as equivalent to
quotes or angle brackets, failing to interpret elements as hex-encoded.
This was a bug, corrected in this patch by processing content as a
sequence of hex-encoded bytes with arbitrary whitespace.

The original generating code emitted the property as individual
elements.  Replace that with generation of a single structure
initializer, which is more useful in cases where the length of a
property value may vary between nodes.

74818bcb49 scripts/dts: Treat array always as a list
If the type of property is a 'array' we should generate defines as
if its a list even if theres only a single element in the list.

983b493ac1 scripts/dts: Add support for enum's
Add specific enum generation support related to usb 'maximum-speed'
property.  This will generate a define with _ENUM with the integer
value of the enum as its ordered in the YAML.  The assumption right
now is that there's a matching enum in the code.

f5b17d4138 scripts/dts: Call /foo/bar a "path" instead of an "address"
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.

7df60372c2 scripts/dts: Rename convert_string_to_label() to str_to_label()
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.

35ecc78cdf scripts/dts/extract: Generate unique defines based on compat & instance
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>.

35afcc9c12 scripts: extract_dts_includes: remove passing yaml param to functions
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.

a7c430f36f scripts: dts: Use DT_ prefix in generated labels
Almost all labels generated by the extracting script are now prefixed
with DT_. The only exceptions are:
- stuff with 'base_label' specified in yaml bindings
- items specified by 'regs_config' and 'name_config' dictionaries
  in globals.py module
- FLASH related labels generated by flash.extract() called separately
  from generate_node_definitions(), e.g. FLASH_WRITE_BLOCK_SIZE -
  these are used directly, not through fixups, from existing code
  so I didn't want to touch them now

Labels generated for aliases are additionally prefixed with information
from the 'compatible' property, e.g. DT_GPIO_LEDS_LED0_* is generated
instead of LED0_*. To provide backward compatibility for code that uses
LEDx_* and SWx_* labels in their previous forms, a command line option
named 'old-alias-names' is added to the extraction script. This option
causes that the labels for aliases are generated in both old and new
forms. Currently this option is always enabled in dts.cmake.

fc5e23365e dts: Add proper handling for boolean properties
We've never handled boolean properties well, if we had a boolean that
existed we'd generate a define of 'True' and if the boolean didn't exist
than nothing would be generated.  So there was no easy way to tell that
the boolean wasn't defined.

Now if we mark a property as boolean in the yaml, we will generate a
define for it regardless if it exists or not.  If it exists we'll
set the value to 1, and if it doesn't to 0.

Fixes #8376
