    airoha: an7583: add NPU nodes and enable kernel config
    
    Add relevant nodes for NPU support for Airoha AN7583 and enable the
    kernel config to enable support in the Airoha Ethernet driver.
    
    NPU firmware is scheduled to be upstreamed to linux-firmware and will be
    added once present upstream.
