rockchip: clk: rk3368: add support for GMAC (SLCK_MAC) clock
To enable the GMAC on the RK3368, we need to set up the clocking
appropriately to generate a tx_clk for the MAC.
This adds an implementation that implements the use of the <&ext_gmac>
clock (i.e. an external 125MHz clock for RGMII provided by the PHY).
This is the clock setup used by the boards currently supported by
U-Boot (i.e. Geekbox, Sheep and RK3368-uQ7).
This includes the change from commit
- rockchip: clk: rk3368: define GMAC_MUX_SEL_EXTCLK
