Subject: [PATCH v4 14/15] ACPI / scan: Create platform device for INT3515 ACPI nodes

The ACPI device with INT3515 _HID is representing a complex USB PD
hardware infrastructure which includes several I2C slave ICs.

We add an ID to the I2C multi instantiate list to enumerate
all I2C slaves correctly.
