> The generic ehci-driver (ehci-generic.c) will try to enable the clocks
> listed in the DTSI. If this fails (e.g. due to clk_enable not being
> implemented in a driver and -ENOSYS being returned by the clk-uclass),
> the driver will bail our and print an error message.
> 
> This implements a minimal clk_enable for the RK3288 and supports the
> clocks mandatory for the EHCI controllers; as these are enabled by
> default we simply return success.
