[PATCH 1/2] clk: imx7d: correct enet clock CCGR register offset

Correct enet clock CCGR register offset.

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

IMX7D_ENET_PHY_REF_ROOT_DIV supplies clock for PHY,
no gate after this clock, its parent clock root has gate.
IMX7D_ENET1_REF_ROOT_DIV/IMX7D_ENET2_REF_ROOT_DIV supplies clocks
for enet IPG_CLK_RMII, no gate after the clock, its parent
clock root has gate.

IMX7D_PLL_ENET_MAIN_125M_CLK (anatop pll) supplies clock for
enet RGMII tx_clk.

Based on Andy Duan's patch from the NXP kernel tree.
