The software interface to these modules is based on Intel MEI framework. Usually mei client devices are dynamically created, so the info of consumers depending on mei client devices is not present in the firmware tables. This causes problems with the probe ordering with respect to drivers for consumers of these mei client devices. But on these camera sensor devices, the ACPI nodes describing the sensors all have a _DEP dependency on the matching mei bus ACPI device, so adding IVSC mei bus ACPI device to acpi_honor_dep_ids allows solving the probe-ordering problem by delaying the enumeration of ACPI-devices which have a _DEP dependency on an IVSC mei bus ACPI device. On TGL platform, the HID of IVSC mei bus ACPI device is INTC1059, and on ADL platform, the HID is INTC1095. So add both of them to acpi_honor_dep_ids.
