ACPI: fan: Use platform device for devres-related actions

Browse source

[ Upstream commit d91a1d129b ]

Device-managed resources are cleaned up when the driver unbinds from
the underlying device. In our case this is the platform device as this
driver is a platform driver. Registering device-managed resources on
the associated ACPI device will thus result in a resource leak when
this driver unbinds.

Ensure that any device-managed resources are only registered on the
platform device to ensure that they are cleaned up during removal.
