[Unstable/OEM-5.13/OEM-5.14] [PATCH 1/1] UBUNTU: SAUCE: r8169: Disable ASPM L1.2

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1942830

There's a r8169 ethernet NIC that has abysmal TX/RX speed, because it
requires longer time to exit from ASPM L1.1/L1.2 than it advertises.

Changing its LTR to a smaller value doesn't help, so in addition to ASPM
L1.1, also disable ASPM L1.2.
