Nitin Joshi 3feb52a2b8 platform/x86: thinkpad_acpi: sysfs interface to get wwan antenna type
On some newer Thinkpads we need to set SAR value based on antenna type.
This patch provides a sysfs interface that userspace can use to get
antenna type and set corresponding SAR value, as is required for FCC
certification.
