Subject: [PATCH] clk: ingenic: Mark ingenic_tcu_of_match as __maybe_unused

This device id table is passed to of_match_node() later on in probe, but
on CONFIG_OF=n builds of_match_node() doesn't do anything with the
arguments. Lets just mark the table unused so that the compiler doesn't
complain about this.
