asoc: add machine driver for sa8155 based automotive platform

Add machine driver for SA8155 based automotive platform,
which is based on mobile machine driver with addition of
extended support for TDM interfaces which is used for data
transfer between SA8155 SoC and the automotive COODEC H/W.
Changes include TDM backend and refactored automotive
frontend DAI links as well as kcontrol functions to
configure TDM slot and offset configuration.

Add 815x machine driver init wrapper to allow registration
of multiple machine driver in single module init call.
