[PATCH v2 0/1] hwmon: (applesmc) Convert to hwmon_device_register_with_info

[Shih-Yuan Lee <fourdollars@debian.org>]

Hi Guenter, Armin, and Henrik,

This is v2 of the patch series converting the applesmc driver from using
the deprecated hwmon_device_register() function to the modern
hwmon_device_register_with_info() API.

Changes in v2:
- Abandon the minimal dummy registration approach in v1.
- Fully convert the driver to modern HWMON ABI standards by dynamically
  allocating temp and fan channels at initialization.
- Rename legacy non-standard attributes to comply with the standard HWMON ABI:
  - fanX_output -> fanX_target (HWMON_F_TARGET)
  - fanX_manual -> pwmX_enable (HWMON_PWM_ENABLE)
- Dynamically register the remaining non-standard fanX_safe attributes
  under HWMON class directory via extra_groups.
- Load and cache fan positions in smcreg.fan_positions to support returning
  labels by reference in .read_string.
- Clean up unused static attribute groups and show/store callback functions
  to avoid unused symbol compiler warnings.
- Verified compilation and successfully tested on real MacBook hardware.

We appreciate your review and comments on this proper refactoring.
