ACPI: scan: Add Intel CVS ACPI HIDs to acpi_ignore_dep_ids[]
Some x86/ACPI laptops with MIPI cameras have a INTC10DE or INTC10E0 ACPI device in the _DEP dependency list of the ACPI devices for the camera- sensors (which have flags.honor_deps set). These devices are for an Intel Vision CVS chip for which an out of tree driver is available [1]. The camera sensor works fine without a driver being loaded for this ACPI device on the 2 laptops this was tested on: ThinkPad X1 Carbon Gen 12 (Meteor Lake) ThinkPad X1 2-in-1 Gen 10 (Arrow Lake) For now add these HIDs to acpi_ignore_dep_ids[] so that acpi_dev_ready_for_enumeration() will return true once the other _DEP dependencies are met and an i2c_client for the camera sensor will get instantiated.
