platform/x86: lg-laptop: Change ACPI device id

[ Upstream commit 58a54f27

 ]

The LGEX0815 ACPI device id is used for handling hotkey events, but
this functionality is already handled by the wireless-hotkey driver.

The LGEX0820 ACPI device id however is used to manage various
platform features using the WMAB/WMBB ACPI methods. Use this ACPI
device id to avoid blocking the wireless-hotkey driver from probing.
