ASoC: wsa881x: Remove support for wsa881x 1.x chip revision
On kernel version 4.4, support for wsa881x v1.x can be dropped as it will not ship with any products using this version. CRs-fixed: 1008341 Change-Id: I7a8c28602d6c66b876b1e413791850bcaefdea98 Signed-off-by: Stephen Oglesby <soglesby@codeaurora.org>
