Some members of the Google_Hatch family include a rt5682, but not a speaker amp. When a speaker amp is also present, the first 10EC5682 entry in snd_soc_acpi_intel_cml_machines[] matches, finding the MX98357A as well, resulting in the quirk_data field in the snd_soc_acpi_mach being non-null. When only the rt5682 is present, the second 10EC5682 entry is matched instead and quirk_data is left null. The sof_rt5682 driver's DMI data matching identifies that a speaker amp is present for all Google_Hatch family devices. Detect cases where there is no speaker amp by checking for a null quirk_data in the snd_soc_acpi_mach and remove the speaker amp bit in that case.
