PCI: dwc: Fix PORT_LINK_CONTROL update when CDM check enabled
If CDM_CHECK is enabled (by the DT "snps,enable-cdm-check" property), 'val'
is overwritten by PCIE_PL_CHK_REG_CONTROL_STATUS initialization. Commit
ec7b952f453c ("PCI: dwc: Always enable CDM check if "snps,enable-cdm-check"
exists") did not account for further usage of 'val', so we wrote improper
values to PCIE_PORT_LINK_CONTROL when the CDM check is enabled.
Move the PCIE_PORT_LINK_CONTROL update to be completely after the
PCIE_PL_CHK_REG_CONTROL_STATUS register initialization.
