That setting is not wrong, but is it sufficient?

see e.g. what we set for existing platforms which need 24 Mhz in this driver:

DMI quirks:

{
.callback = sof_rt5682_quirk_cb,
.matches = {
DMI_MATCH(DMI_PRODUCT_FAMILY, "Google_Hatch"),
},
.driver_data = (void *)(SOF_RT5682_MCLK_EN |
SOF_RT5682_MCLK_24MHZ |
SOF_RT5682_SSP_CODEC(0) |
SOF_SPEAKER_AMP_PRESENT |
SOF_RT5682_SSP_AMP(1)),
},

Board-id quirks:

{
.name = "jsl_rt5682_rt1015",
.driver_data = (kernel_ulong_t)(SOF_RT5682_MCLK_EN |
SOF_RT5682_MCLK_24MHZ |
SOF_RT5682_SSP_CODEC(0) |
SOF_SPEAKER_AMP_PRESENT |
SOF_RT1015_SPEAKER_AMP_PRESENT |
SOF_RT5682_SSP_AMP(1)),
},

You probably need a board-id quirk dedicated to CML, rather than override the TGL one?
