[v13,03/21] clk: Unconditionally recursively en-/dis-able clocks

For clocks not in the CCF, their parents will not have UCLASS_CLK, so we
just enable them as normal. The enable count is local to the struct clk,
but this will never result in the actual en-/dis-able op being called
(unless the same struct clk is enabled twice).

For clocks in the CCF, we always traverse up the tree when enabling.
Previously, CCF clocks without id set would be skipped, stopping the
traversal too early.
