[U-Boot] [PATCH v4 08/13] dm: clk: Define clk_get_parent_rate() for

[sbabic at denx.de]

> This commit adds the clk_get_parent_rate() function, which is responsible
> for getting the rate of parent clock.
> Unfortunately, u-boot's DM support for getting parent is different
> (the parent relationship is in udevice) than the one in common clock
> framework (CCF) in Linux.
> To alleviate this problem - the clk_get_parent_rate() function has been
> introduced to clk-uclass.c.
