platform/x86: asus-wmi: add keystone dongle support
The ASUS Keystone is a physical NFC-like dongle that slots into supported
ASUS laptops. The EC fires WMI notify code 0xB4 on insert/remove events.
Expose the current insert state via a sysfs attribute by querying WMI
device ID 0x00120091 (DSTS). This devid does not follow the standard DSTS
convention: PRESENCE_BIT (0x00010000) encodes the insert state rather than
feature presence, and STATUS_BIT is never set. Presence of a keystone slot
is detected by a successful DSTS call.
