Rockpro64 PCI-Express Issue.

I am getting the following with the unpatched Debian unstable kernel and an ASMedia-based 4-Port SATA card inserted:

Code:

root@devuan:~# lspci -vvv|grep Speed
               LnkCap: Port #0, Speed 2.5GT/s, Width x4, ASPM L1, Exit Latency L0s <256ns, L1 <8us

               LnkSta: Speed 2.5GT/s, Width x1, TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt-
               LnkCtl2: Target Link Speed: 2.5GT/s, EnterCompliance- SpeedDis-
               LnkCap: Port #1, Speed 5GT/s, Width x1, ASPM not supported, Exit Latency L0s unlimited, L1 <2us
               LnkSta: Speed 2.5GT/s, Width x1, TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt-

Edit: Tried with latest 5.7-rc2 kernel from Armbian: same result
Edit2: Tried with 5.4.32 kernel with rockchip-specific patches from Armbian: same result

Both kernels hang with the inserted PCIe x4 gigabit card, and both also boot fine with the inserted NVMe card (just like the regular Debian unstable kernel).

@pgwipeout Patches highly appreciated, but if it's just the single change you mentioned this should be already sufficient.
