Subject: [PATCH 4/4] ASoC: simple-card: parse symmetric-clock-roles property

From: Alvin Šipraga <alsi@...g-olufsen.dk>

The property, when set, specifies that both ends of the dai-link should
have the same clock consumer/provider roles. As with other simple-card
properties, a prefix can be specified.
