clk: Ignore disabled DT clock providers
of_clk_init() uses for_each_matching_node_and_match() to find clock
providers, which returns all matching device nodes, whether they are
enabled or not. Hence clock providers that are disabled explicitly in DT
using e.g.
"status = "disabled";
are still activated.
Add a check to ignore device nodes that are not enabled, like
of_irq_init() does.
