    kernel: export switch_generic_set_link() symbol
    
    This fixes:
    ERROR: "switch_generic_set_link" [drivers/net/phy/b53/b53_common.ko] undefined!
    
    At some point all packages for swconfig drivers were dropped and targets
    were meant to have them built into kernels. It seems b53 (re-)gained its
    kmod-switch-bcm53xx however and b53 needs to be built as module.
    
    Fixes: b2cfed48f626 ("Revert "swconfig: fix Broadcom b53 support"")
