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.
