Correct enet clock gates as below: CCGR6: IMX7D_ENET_AXI_ROOT_CLK (enet1 and enet2 bus clocks) CCGR112: IMX7D_ENET1_TIME_ROOT_CLK, IMX7D_ENET1_IPG_ROOT_CLK CCGR113: IMX7D_ENET2_TIME_ROOT_CLK, IMX7D_ENET2_IPG_ROOT_CLK Just rename unused IMX7D_ENETx_REF_ROOT_CLK for IMX7D_ENETx_IPG_ROOT_CLK instead of adding new clocks. Based on Andy Duan's patch from the NXP kernel tree.
