    loongarch64: add Loongson PCI DWMAC as built-in
    
    Add the CONFIG_DWMAC_LOONGSON driver to the loongarch64 kernel
    configuration as a built-in module.
    
    This driver is required for the integrated Ethernet controller found on
    modern Loongson devices such as the 3A6000 NUC and 2K3000. Including it
    by default ensures these popular devices have network functionality
    out-of-the-box.
    
    Configuration changes were made via `make kernel_menuconfig` for the
    loongarch64 target.
