If a 'set_bclk_ratio' call is attempted on a DAI not implementing the
method, make it an -ENOSUPP error instead of -EINVAL. Assume the DAI can
still be okay with the ratio, just does not care to register a handler.
No current in-tree users of snd_soc_dai_set_bclk_ratio seem to inspect
the return value, but -ENOSUPP disables an error print from within the
common soc_dai_ret return filter. With the new behavior a machine
driver can do a blanket 'set_bclk_ratio' on all DAIs on a bus, some of
which may care about the ratio, some of which may not.
