sysfs attrs for adt7410 are supposed to be created under
the hwmon device, but are being created under the i2c
device.
Switch to hwmon_device_register_with_groups to create
the relevant attrs in the correct directory, and
to also fix the deprecation warning created by
hwmon_device_register.
To achieve this, the following changes are also made.
* pass client name from adt7410 driver to common
driver and use it to register hwmon device
* remove attribute_group declaration and use the
ATTRIBUTE_GROUPS macro to align with other
usages of hwmon_device_register_with_groups
* remove name attribute since it is not needed anymore
after moving away from hwmon_device_register
* store bus device into private data and use it to call
the i2c/spi ops both in hwmon sysfs attr contexts and
outside of them
