If size or address cells happened to be 2 we'd get the wrong value since
we where shift the least significant 32-bit's up. Adjust the math based
on the value of the cell amount to fix things.

Rename address / size cell variable to clarify that its the number
of address / size cells.

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.

Before dtc 1.4.7 we'd get something like the following for an interrupt
property in which #interrupt-cells is 2.
interrupts = <1 2 3 4>;
After dtc 1.4.7 we get:
interrupts = <1 2>, <3 4>;
We should handle both cases in the extract interrupt handling code. So
if we see a list of lists, we flatten it to a single list to normalize
the property.
Fixes: #9558

A node alias name should be applied to the all property names.
Before this patch, the alias name is applied erroneously
just for CLOCK_CONTROLLER, skipping the CLOCK_BITS and CLOCK_BUS
property names.

When a DTS node has no 'compatible' property and its parent node has a
list for its compatible property, return only the first element of the
parent's compatible list.

'defs' variable is used and passed as a parameter in the vast
majority of the functions of extract_dts_includes script.
Set this variable global
Do the same with 'struct' variable for upcoming change.

Treat new generated dtc element 'alt-name' as usual aliases.
Aim is not to duplicate generation of node elements but provide
pointers using generic alternate names.
For instance, defining following overriding node:
arduino_i2c : i2c1 {};
Will generate following definition:
#define ARDUINO_I2C_LABEL ST_STM32_I2C_V1_40005400_LABEL
Then 'ARDUINO_I2C_LABEL' could be use a generic binding.

In some cases, node label could be generated with "/" character
in name string, which prevents compilation

Modify get_compat function to look for 'compatible' property
in parent nodes if not available at node level.
Since this operation is quite common, this allows some code
factorization. As a consequence, get_compat takes 'node_address'
as argument instead of 'node'.
