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.

Changes in v4: None Changes in v3:
- The rate information is now cached into struct clk field
- The clk_get_parent() is used to get pointer to the parent struct

This also needs a test.
Please find corresponding test:

which covers clk_get_parent() and clk_get_parent_rate() as well.
