net: stmmac: dwmac-loongson: Use PCI_DEVICE_DATA() macro for device identification

For the readability sake convert the hard-coded Loongson GMAC PCI ID to
the respective macro and use the PCI_DEVICE_DATA() macro-function to
create the pci_device_id array entry. The later change will be
specifically useful in order to assign the device-specific data for the
currently supported device and for about to be added Loongson GNET
controller.
