The CS35L45 has SYNC pin that can be used as a multi
device synchronization (MDSYNC) bus. This pin can send
various message types between Cirrus devices.

This patch series adds support for long and short DSP
messages between CS35L45 devices. 

Each device on the SYNC bus must have a unique transmitter
identifier per message type as the bus arbitrates message
priority via this identifier. These identifiers are set by
the introduced devicetree properties. The priority 
assignment is intended to be a static system integration
decision.

The relevant receiver controls are introduced as mixer
controls so they are exposed at runtime to be configured
for the appropriate use cases.

Changes since v1:
 - Fixed property parsing namespace issue
