platform/x86: thinkpad_acpi: Ignore battery threshold change event notification

[ Upstream commit 29e4e6b4235fefa5930affb531fe449cac330a72 ]

If user modifies the battery charge threshold an ACPI event is generated.
Confirmed with Lenovo FW team this is only generated on user event. As no
action is needed, ignore the event and prevent spurious kernel logs.
