64995e2a54 max17055: Set battery parameters from device tree 
Currently the MAX17055 driver assumes that a battery matching the
default characteristics is used.

This change allows battery characteristics to be specified in device
tree and writes them to the MAX17055 on initialization.

Existing default values are maintained for backwards compatibility.

Initialization routine taken from MAX17055 Software Implementation
Guide, document UG6365.

893857b48a max17055: Fix current conversion from MAX17055 unit to milliamps 
`SENSOR_CHAN_GAUGE_AVG_CURRENT` is currently treated as a capacity
by the MAX17055 driver, however the unit conversion is different
for current and must be calculated separately.

Add a separate method to convert a current reading to milliamps
from 1.5625 uV/R_SENSE units, instead of the 5uVH/R_SENSE conversion
that was previously used.

Tested by comparing value read and converted from MAX17055 with
value from an external power profiling kit.

5f605fd5ab drivers: sensor: Convert drivers to new DT device macros 
Convert sensor drivers from:

    DEVICE_AND_API_INIT -> DEVICE_DT_INST_DEFINE
    DEVICE_GET -> DEVICE_DT_INST_GET
    DEVICE_DECLARE -> DEVICE_DT_INST_DECLARE

etc..

8b47e563e2 dts/Kconfig: Remove HAS_DTS_I2C 
HAS_DTS_I2C is now selected by I2C and
always used as I2C && HAS_DTS_I2C.

It could then be purely removed.

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
