Same language nits as for patch 1/1.

I tried this patch along with the DT changes and the link on the CRD
still comes up as 2-lane:

	qcom-pcie 1bf8000.pci: PCIe Gen.4 x2 link up

so something appears to be wrong here. (I noticed the same with your
next branch last week.)

How did you test this? Does the link actually come up as 4-lane for you?
