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.
