The name clk_provider_set_rate would be a good hint that it's an API for
clock providers not consumers.

The name clk_core_set_rate would be a good hint that the function takes
a clk_core object rather than the clk (client) object.

Neither names see too unwieldy to me.

Anyway, that's the color of my bikeshed:-)
