[PATCH v3 0/1] clk: Clean up optional helpers, and add API docs to HTML

[Sean Anderson <seanga2@gmail.com>]

This cleans up the various optional helpers for clocks, and adds a new one.
While we're at it, also convert the existing API docs to our HTML documentation.

The rest of this series has been applied, but the former patch 5 had an error,
so I did not apply it. I have fixed it in this revision.

Changes in v3:
- Fix clk_get_by_name_optional recursing

Changes in v2:
- Rebased onto u-boot/master
