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

This is configuring DSP A identically to left justified mode, it looks
like the format configuration needs at least some interlock with the TDM
configuration.
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.
