phy fixes:
 *) Add a empty function for phy_reset when CONFIG_GENERIC_PHY is not set
 *) change the phy lookup table for da8xx-usb to match it with the name
    present in the board configuraion file (used for non-dt boot)
 *) Fix incorrect programming sequence in w.r.t deassert of phy_rst
    in phy-rockchip-pcie
 *) Fix to avoid NULL pointer dereferencing error in sun4i phy
