r8169: avoid link-up interrupt issue on RTL8106e if user enables ASPM 

[ Upstream commit 1ee8856de82faec9bc8bd0f2308a7f27e30ba207 ]

It has been reported that on RTL8106e the link-up interrupt may be
significantly delayed if the user enables ASPM L1. Per default ASPM
is disabled. The change leaves L1 enabled on the PCIe link (thus still
allowing to reach higher package power saving states), but the
NIC won't actively trigger it.
