PCI: dwc: Always enable CDM check if "snps,enable-cdm-check" exists

If the "snps,enable-cdm-check" property exists, we should enable the CDM
check.  But previously dw_pcie_setup() could exit before doing so if the
"num-lanes" property was absent or invalid.

Move the CDM enable earlier so we do it regardless of whether "num-lanes"
is present.
