On Asus GL502VSK and UX305LA, ACPI incorrectly reports discharging when
battery is full and AC is plugged.
However rate_now is correct under this circumstance, hence we can use
"rate_now == 0" as a predicate to report battery full status correctly.

The Realtek r8153 ethernet does not work on Genesys Logic hub, no-lpm
quirk can make it work.
Since another r8153 dongle at my hand does not have the issue, so add
the quirk to the hub instead.
