The boundary checks in airoha_clk_enable(), airoha_clk_get_rate(), and
airoha_clk_set_rate() use "id > data->num_clocks" which allows id equal
to num_clocks to pass. Since data->descs[] has exactly num_clocks entries
(indices 0 to num_clocks-1), id=num_clocks results in an out-of-bounds
array access.
This is currently not triggered because the device tree clock IDs are
within bounds, but the check should be defensive. Fix by changing the
comparison from ">" to ">=".
