[PATCH] clk: Constify parent name arrays

[PATCH] clk: Constify parent name arrays

[Mark Brown]

Drivers should be able to declare their arrays of parent names as const
so the APIs need to accept const arguments.

We should probably have a MAINTAINERS entry for the clk API...

Slight oversight in this one and the updates for the new API version
were simpler than I thought so sending a new version shortly.
