When driver is probed, we iterate over NHLT and check if clk entries are
present. For each such entry we call register_skl_clk and keep the
result in data->clk[].
Currently data->clk is sparsely indexed using NHLT table iterator, while
when freeing we use number of registered entries. Let's just use
data->avail_clk_cnt as index, so it can be reset back in
unregister_src_clk.
