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:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

49f2167974 emul: i2c: Add support for I2C emulators
Add an emulation controller which routes I2C traffic to attached
emulators depending on the I2C address selected. This allows drivers
for I2C peripherals to be tested on systems that don't have that
peripheral attached, with the emulator handling the I2C traffic.
