[PATCH net-next 2/2] r8169: change the L0/L1 entrance latencies for RTL8106e

The original L0 and L1 entrance latencies of RTL8106e are 4us. And
they cause the delay of link-up interrupt when enabling ASPM. Change
the L0 entrance latency to 7us and L1 entrance latency to 32us. Then,
they could avoid the issue.
