ACPI / scan: Create platform device for fwnodes with multiple i2c devices
Some devices have multiple I2cSerialBus resources and for things to work an i2c-client must be instantiated for each, each with its own i2c_device_id. Normally we only instantiate an i2c-client for the first resource, using the ACPI HID as id. This commit adds a list of HIDs of devices, which need multiple i2c-clients instantiated from a single fwnode, to acpi_device_enumeration_by_parent and makes acpi_device_enumeration_by_parent return false for these devices so that a platform device will be instantiated. This allows the drivers/platform/x86/i2c-multi-instantiate.c driver, which knows which i2c_device_id to use for each resource, to bind to the fwnode and initiate an i2c-client for each resource.
