Rockchip RK3528 (and RV1106) has a different integrated PHY compared to
the integrated PHY on RK3228/RK3328. Current powerup/down operation is
not compatible with the integrated PHY found in these SoCs.
Move the rk_gmac_integrated_phy_powerup/down functions to top of the
file to prepare for them to be called directly by a GMAC variant
specific powerup/down operation.
