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?
