acer-wmi: schedule threeg and interface sysfs for feature removal
we can now autodetect internal 3G device and already have the threeg rfkill device. So, we plan to remove threeg sysfs support for it's no longer necessary. We also plan to remove interface sysfs file that exposed which ACPI-WMI interface that was used by acer-wmi driver. It will replaced by information log when acer-wmi initial. We keep it around for userspace compatibility reasons, schedule removal in 2012.
