pc87360: Delete sysfs files on device deletion
pc87360: Delete sysfs files on device deletion Add 4 explicit attribute groups for the 5 sensor types: voltage (in), therm, temp, and fan & pwm (together in one group). Use sysfs_remove_group() to drop them, but keeps the existing startup code, which calls device_create_file in loops.
