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
