I think it would be better to configure pcs_misc *before* pcs.
That would be closer to what downstream does (for 835 and 845 at least).

Also you don't need to test for NULL as that is already done in
qcom_qmp_phy_configure() -- and in fact even that test is redundant,
since the array is not dereferenced when count is 0.

When are you planning on sending a v2 of your PCIe series?
