SCLK_GMACx therefore keeps whatever parent the bootloader or the hardware reset left, which may or may not be the internal CLK_MACx_2TOP. Add CLK_MACx_2TOP as the parent of SCLK_GMACx explicitly, so the GMAC main clock always comes from the internal clock source and does not depend on the bootloader state. The rate assignment is unchanged: SCLK_GMACx_RX_TX stays at 0 (managed at runtime by rk_set_clk_tx_rate()), SCLK_GMACx stays at 125 MHz.
