ASoC: SOF: imx8: use common imx chip interface

The common interface for imx chips (defined in imx-common.c) contains the
definitions for a lot of functions required by the SOF core. As such, the
platform driver can just use the common definitions instead of duplicating
code by re-defining aforementioned functions.

Make the transition to the new common interface. This consists of:

  1) Removing unneeded functions, which are already defined in the
  common interface.

  2) Defining some chip-specific operations/structures required by the
  interface to work.

  3) Dropping structure definitions that are no longer needed.

  4) Adapting some existing functions to the new interface.
