ANDROID: GKI: phy: add Android ABI padding to some structures

Browse source 
Try to mitigate potential future driver core api changes by adding a
padding to stuct phy_device and struct phy_driver

Inspired by the upstream changes in 5.4.26 and 4.19.111

This includes the ABI update for the change as well:

    function phy_device* phy_connect(net_device*, const char*, void ()*, phy_interface_t)
    function void phy_disconnect(phy_device*)
    function int phy_mii_ioctl(phy_device*, ifreq*, int)
    function void phy_print_status(phy_device*)
    function void phy_start(phy_device*)
    function void phy_stop(phy_device*)
