ACPI: fan: Separate file for attributes creation
Move the functionality of creation of sysfs attributes under acpi device
to a new file fan_attr.c. This cleans up the core fan code, which just
use thermal sysfs interface. The original fan.c is renamed to
fan_core.c.
No functional changes are expected.
