ASoC: Remove unused DAI format defines

The defines for TDM and synchronous clocks are not used - they are
mostly a legacy of the automatic clocking configuration.  TDM will
require configuration of the number of timeslots and which ones to use
so can't be fit into the DAI format and synchronous mode is handled by
symmetric_rates (and needs to be done by constraints rather than when
the DAI format is being configured).
