Gerard Marull-Paretas fb60aab245 drivers: migrate includes to <zephyr/...> 
In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Tomasz Bursztyka 4dcfb5531c isr: Normalize usage of device instance through ISR 
The goal of this patch is to replace the 'void *' parameter by 'struct
device *' if they use such variable or just 'const void *' on all
relevant ISRs

This will avoid not-so-nice const qualifier tweaks when device instances
will be constant.

Note that only the ISR passed to IRQ_CONNECT are of interest here.

In order to do so, the script fix_isr.py below is necessary:

Finally, some files needed manual fixes such.

Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers 
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

-struct device *
