[U-Boot] [U-Boot, 1/2] rockchip: clk: rk3399: handle clk_enable requests for GMAC

[Philipp Tomsich]

> Since commit ba1f96672522 ("net: designware: add clock support"), the
> designware GMAC driver enables all referenced clocks. While this is a
> no-op for the RK3399 during boot-up (reset behaviour has all the clock
> gates open anyway), we still need to handle the clock-ids passed in
> the enable op of the clock-driver and return a success.
> 
> This change extends the enable-op of the rk3399 clk driver to signal
> success to the caller when the clocks for the GMAC are enabled.
