media: ipu3-cio2: Add support for instantiating i2c-clients for VCMsHEADmaster
Some sensors come with a variable-focus lens where the lens focus is controller by a VCM (Voice Coil Motor). If there is a VCM for the lens-focus, and if so which one, is described on the vcm_type field of the ACPI SSDB table. These VCMs are a second I2C device listed as an extra I2cSerialBusV2 resource in the same ACPI device as the sensor. The i2c-core-acpi.c code only instantiates an i2c-client for the first I2cSerialBusV2 resource. Add support for instantiating an i2c-client for the VCM with the type of the i2c-client set based on the SSDB vcm_type field.
