Some CPU drivers (e. g. davinci-mcasp) may require the system clock to
be configured as OUT, while there's no good way currently to set
SND_SOC_CLK_OUT in simple-soc driver if the clock is fixed-rate.
This patch makes asoc_simple_card_init_dai() initialize clock to
SND_SOCK_CLK_OUT if explicitly stated in the relevant dts file. This
change is transparent and doesn't change the default behavior.

snd_soc_of_parse_card_name() doesn't return an error if the requested
property isn't present, but silently fails to fill the card name. This can
not be changed, as it is a backwards compatibility measure itself.
We can not rely on the return value of this function alone, but must check
if the card name has been filled sucessfully when deciding to skip the
fallback path, which is in place for existing users.

Fix inconsistent use of of_graph_get_port_parent() where
asoc_simple_card_parse_graph_dai() does of_node_get() before
calling it while other callers do not. We can fix this by
not trashing the node passed to of_graph_get_port_parent().
Let's also make sure the callers have correct refcounts and remove
related incorrect of_node_put() calls for of_for_each_phandle
as that's done by of_phandle_iterator_next() except when
we break out of the loop early.
Let's fix both issues with a single patch to avoid kobject
refcounts getting messed up more if two patches are merged
separately.
Otherwise strange issues can happen caused by memory corruption
caused by too many kobject_del() calls such as:
BUG: sleeping function called from invalid context at
kernel/locking/mutex.c:747
...
(___might_sleep)
(__mutex_lock)

>From OF-graph point of view, it should have

But current driver doesn't care about 2nd connection
of Codec, because it is dummy from DPCM point of view.
This patch can care 2nd Codec connection, and it should be
supported from OF-graph point of view.
