g762_remove() needs to first call hwmon_device_unregister() and then
g762_of_clock_disable(). For that reason, it is not possible to
convert it to devm_hwmon_device_register_with_groups() and the
the non device managed version must be used.
This is correctly stated in commit message for 398e16db6262 ("hwmon:
(g762) Convert to hwmon_device_register_with_groups") but the
associated changes do in fact introduce a call to the device managed
version of the function.
This patch fixes that typo by switching to the non devm_ version.

Use ATTRIBUTE_GROUPS macro and hwmon_device_register_with_groups() to simplify
the code a bit.
Use hwmon_device_register_with_groups rather than the device managed version to
ensure g762_of_clock_disable() is called after hwmon_device_unregister().

Make of_device_id array const, because all OF functions
handle it as const.

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

GMT G762/763 fan speed PWM controller is connected directly to a fan
and performs closed-loop or open-loop control of the fan speed. Two
modes - PWM or DC - are supported by the chip. Introduced driver
provides various knobs to control the operations of the chip (via
sysfs interface). Specific characteristics of the system can be passed
either using board init code or via DT. Documentation for both the
driver and DT bindings are also provided.
