The Lenovo Yoga Pro 7 14ASP9 (83HN) has no digital microphone on the ACP
PDM interface; all internal mics are wired to the Realtek ALC287 codec.
Add 83HN to acp70_acpi_flag_override_table to prevent the legacy ACP
driver from binding and exposing a non-functional PDM capture device,
consistent with the sibling 83W5/83V9 entries.
