The pci_host_common_parse_port() shouldn't decide whether to fall back
to the legacy RC-level binding by checking for "reset-gpios/reset-gpio"
properties on the RC node and returning -ENODEV. That's a policy
decision belongs to the caller, not this common helper.
This patch set improves the PERST# (PCIe reset) GPIO fallback logic
across the generic PCI host bridge helper and the i.MX6 PCIe driver.

The pci_host_common_parse_port() shouldn't check the RC-level binding.
That's a policy decision that belongs to the caller, not this common
helper.
Simplify pci_host_common_parse_port() to only parses properties from the
Root Port(and its children) without checking the RC node. Also change
pci_host_common_parse_ports() to return 0 when no ports are found, since
it is not an error.
So now both functions won't return failure for "property not found" or
"port not found", they purely returns 0 on success and a negative error
code on real failures.

Since pci_host_common_parse_port() doesn't return failure for "property
not found"(-ENODEV), the caller should inspect the parsed result and
decide whether to fall back to the legacy binding.
Add imx_pcie_perst_found() to inspect the parsed result.
