ARM: dts: msm: Add SPDIF support for qcs405 



Add support for SPDIF interfaces on qcs405.
The SPDIF interfaces are inside LPASS and are used with optical or
coaxial SPDIF jack and with audio return channel (ARC) from HDMI sink.
SPDIF is a one-wire serial audio interface that is commonly use in
consumer electronic products to transfer stereo PCM or multichannel
compressed audio formats between devices.
