[U-Boot] [PATCH v5 04/18] clk: Extend struct clk to provide information regarding clock rate
This commit extends the struct clk to provide information regarding the
clock rate.
As a result the clock tree traversal is performed at most once, and further
reads are using the cached value.

Changes in v5:
- Use long long to store rate value (to avoid int overflow and also return
errors correctly)
