HID: wacom: Remove AES power_supply after extended inactivity
Even if a user does not use their AES pen for an extended period,
the battery power supply attributes continue to exist.
This results in the desktop showing battery status for a pen
that is no longer in use and which may in fact be in a different
state (e.g. the user may be charging the pen).
To avoid confusion and ensure userspace has an accurate view
of the battery state, this patch automatically removes
the power_supply after 30 minutes of inactivity.
