Subject: [PATCH v2 0/2] clk: implement a new managed helper and add first
 user

I'm posting this as RFC to see if there's any interest. I noticed that
some drivers do: clk_get() -> clk_set_rate() -> clk_prepare_enable(). I
was wondering if it's worth factoring this out into dedicated helpers.

This series adds a new such helper for the "optional-enabled" use-case
and the first user. Let me know if this makes sense.
