TDM mode for max98090 is dsp_a compatible. So allow it.

According to datasheet MAX98090 supports only DSP_A (L data MSB after FRM LRC) TDM mode. Allowing this mode will let us proper configure CPU audio node via DT. Actual TDM mode activation is performed in max98090_set_tdm_slot() via M98090_REG_TDM_FORMAT/M98090_REG_TDM_CONTROL registers.
