PATCH 1/2 clk: Mark 'all_lists' as const

This list array doesn't change at runtime. Mark it const to move to RO memory.

PATCH 2/2 clk: Mark clk_core_evict_parent_cache_subtree() 'target' const

In reply to Stephen Boyd

Clarify that the 'target' clk isn't being modified, instead it's being searched for. Mark it const so the function can't modify it.
