Guenter Roeck a5c47c0d38 hwmon: Introduce SENSOR_DEVICE_ATTR_{RO, RW, WO} and variants
Introduce SENSOR_DEVICE_ATTR_{RO,RW,WO} and SENSOR_DEVICE_ATTR_2_{RO,RW,WO}
as simplified variants of SENSOR_DEVICE_ATTR and SENSOR_DEVICE_ATTR_2 to
simplify the source code, improve readbility, and reduce the chance of
inconsistencies.

Lucas Magasweran 59df4f4e8e hwmon: (core) check parent dev != NULL when chip != NULL
hwmon_device_register_with_info() registration API requires a
non-NULL parent device when chip is non-NULL.

This commit adds a check and documents this requirement.

Guenter Roeck 848ba0a2f2 hwmon: (core) Rename groups parameter in API to extra_groups
The 'groups' parameter of hwmon_device_register_with_info() and
devm_hwmon_device_register_with_info() is only necessary if extra
non-standard attributes need to be provided. Rename the parameter
to extra_groups and clarify the documentation.

Guenter Roeck af1bd36c06 hwmon: (core) Deprecate hwmon_device_register()
Inform the user that hwmon_device_register() is deprecated,
and suggest conversion to the newest API. Also remove
hwmon_device_register() from the kernel API documentation.

Note that hwmon_device_register() is not marked as __deprecated()
since doing so might result in build errors.

Guenter Roeck f4d325d5ed hwmon: (core) Clarify use of chip attributes
Describing chip attributes as "attributes which apply to the entire chip"
is confusing. Rephrase to "attributes which are not bound to a specific
input or output".

Also rename hwmon_chip_attr_templates[] to hwmon_chip_attrs[] to indicate
that the respective strings strings are not templates but actual attribute
names.
