Subject: [PATCH] serial: 8250_pci: Fix ACCES entries in pci_serial_quirks

Fix error in table for PCI_DEVICE_ID_ACCESIO_PCIE_ICM_4S that caused it
and PCI_DEVICE_ID_ACCESIO_PCIE_ICM232_4 to be missing their fourth port.
Fixes: 78d3820b9bd3 ("serial: 8250_pci: Have ACCES cards that use the four port Pericom PI7C9X7954 chip use the pci_pericom_setup()")
