[RFC PATCH 0/2] PCI: rockchip-host: support quirky devices

[Geraldo Nascimento <geraldogabriel@gmail.com>]

With these two changes I'm able to work with a Samsung PM981a OEM SSD
that is known to be not-working with Rockchip-IP PCIe.

Previously I attempted a contrived solution that mostly worked for my
simple purposes but was rather inelegant and impractical.

Now I have isolated the behavior to the three lines in the two commits.
Omit those three lines and you get a working set with the kernel.

I have no idea how to actually implement this in a way that makes sense
and doesn't break the PCIe spec but it is my sincere wish that
interested RK3399 parties test the change and report any regressions
with already-working devices and specifically, successes or failures of
initial link-training with these changes.
