The 'id' field was never used and tended to just have the compat of the
node. Lets remove it and removed some code in extract_dts_includes.py
related to it. Added a warning if 'id' is set in a yaml so we can
remove it going forward.

Add 'generation: define' directive to 'compatible' property.
When existing for a type of device, move compatible property
description in device base structure (eg: i2c.yaml)

'cell_string' yaml attribute has been introduced in order to
help enforcement of specific string during defines generation.
This adds complexity in understanding script behavior as a black
box and create additional dependency which is not strictly required.
For node specific generation functions (pinctrl and interrupts),
this could be replaced directly by an hardcoded version
(as everyone used the same 'cell_string' anyway).
For extract_cells functions, string could be replaced by extracted
property name. As a consequence, we're now able to generate defines
for properties refering to these controllers via phandle.
For instance, in following node
spbtle-rf@0 {
compatible = "st,spbtle-rf";
reg = <0>;
reset-gpios = <&gpioa 8 0>;
};
We'll be able to generate:
#define ST_STM32_SPI_...LE_RF_0_RESET_GPIOS_CONTROLLER "GPIOA"
#define ST_STM32_SPI_...PBTLE_RF_0_RESET_GPIOS_FLAGS_0 0
#define ST_STM32_SPI_..._SPBTLE_RF_0_RESET_GPIOS_PIN_0 8
Only impact for this whole change is for NXP clocks which were the
only ones using 'cell_string' attribute with a value different than
the default one.

Switch the SoC device tree to define a single entry per SERCOM instead
of one per mode.
Define a Device Tree binding for the SAM0 SPI and use it instead of
Kconfig for enabling / disabaling instances
Switch the Arduino Zero, Adafruit Feather M0 Basic Proto, and
Trinket M0 to use the new defintion.
Add the APA102 LED that's on the Trinket as a test.

Configure ccm size and address via dts. According to the DT
specification, the unit-address of a node must match the
first address specified in the reg property of the node.

According to yaml syntaxic rules, 'properties' described in dts
bindings yaml files could be seen as 'mapping'(key/value couple),
instead of 'series' (list of single elements).
yaml 'mappings' will then be converted by yaml python library as
python 'dict' which will ease treatment (instead of current list
as were before this commit).
Same treatment is applied to 'inherits'.
script extract_dts_inlcude is updated to take change of yaml_list
structre into account. This allows some code simplification. Largest
impact is yaml_collapse function which works now allow complete
overload method on all the attributes of a yaml nodes.
