McBSP's data delay can be configured from 0 to 2 bit clock periods. 0 is used for DSP_B format, 1 for DSP_A format. A data delay of 2 bit clock periods can be used to interface to 'T1 framing' devices where data stream is preceded by a 'framing bit'. This 2 bit clock data delay is not described in the bindings.
Add two flags 'ti,T1-framing-[rx/tx]' to enable a data delay of 2 bit clock periods in reception or transmission.
