PCI/AER: Honor "pcie_ports=native" even if HEST sets FIRMWARE_FIRST
According to the documentation, "pcie_ports=native", linux should use
native AER and DPC services. While that is true for the _OSC method
parsing, this is not the only place that is checked. Should the HEST
list PCIe ports as firmware-first, linux will not use native services.
This happens because aer_acpi_firmware_first() doesn't take 'pcie_ports'
into account. This is wrong. DPC uses the same logic when it decides
whether to load or not, so fixing this also fixes DPC not loading.
