CHROMIUM: drivers: ar8216: prevent device duplication in ar8xxx_dev_list
If probe is called twice, once for PHY0 and a second time for PHY4,
the same switch device will be added twice to ar8xxx_dev_list, while
supposedly this list should have one element per hardware switch present
in the system.
While no negative impact have been observed, it does happen if a
platform instanciates these two PHYs from device-tree, as an example.
