r8169: Align ASPM/CLKREQ setting function with vendor driver
There's a small delay after setting ASPM in vendor drivers, r8101 and
r8168.
In addition, those drivers enable ASPM before ClkReq, also change that
to align with vendor driver.
I haven't seen anything bad becasue of this, but I think it's better to
keep in sync with vendor driver.
