The blamed commit functionally changed the error path of
cdns_pcie_host_probe(), now cdns_plat_pcie_probe().
When the old code path executed "goto err_get_sync", the PCIe controller
probe function propagated the pm_runtime_get_sync() error code. The new
code doesn't, and returns 0.
Similarly for the "goto err_init" previously triggered by
cdns_pcie_host_init() errors, and now triggered by
cdns_pcie_host_setup() and cdns_pcie_ep_setup() errors. These are not
propagated and will result in probing success, which is incorrect.
Fixes: bd22885aa188 ("PCI: cadence: Refactor driver to use as a core library")

The tegra as well as a few dwc PCI controller drivers uses PM runtime
operations without including the required <linux/pm_runtime.h> header.
Similarly, pcie-rockchip-host, pcie-starfive as well as a few dwc PCI
controllers use the regulator consumer API without including
<linux/regulator/consumer.h>.
pcie-spacemit-k1.c uses of_get_next_available_child() and of_node_put()
without including <linux/of.h>.
It seems these function prototypes were indirectly provided by
<linux/phy/phy.h>, mostly by mistake (none of the functions it exports
need it).
Before the PHY header can drop the unnecessary includes, make sure the
PCI controller drivers include what they use.

This is practically a full revert of commit
7a4db656a635 ("PCI: dra7xx: Create functional dependency between PCIe and PHY")
and a partial revert of the device link pieces from commits
dfb80534692d ("PCI: cadence: Add generic PHY support to host and EP drivers")
49229238ab47 ("PCI: keystone: Cleanup PHY handling")
The trouble with these commits is that they dereference fields inside
struct phy from a consumer driver, which will become no longer possible.
Since commit 987351e1ea77 ("phy: core: Add consumer device link
support") from 2019, the PHY core also adds a device link to order PHY
provider and consumer suspend/resume operations. All reverted commits
are from 2017-2018, and what they do should actually be redundant now.
