[PATCH v4 5/5] media: ov8858: add ACPI device ID INT3477

[Thierry Chatard <tchatard@gmail.com>]

The Omnivision OV8858 appears in ACPI firmware under the HID INT3477 on
Intel IPU3-based platforms such as the Dell Latitude 5285 2-in-1. Add
INT3477 to the ACPI match table so the driver binds when instantiated by
ipu_bridge.

The supply names array already covers the regulators needed on this
platform: the TPS68470 board data maps VSIO to the "dovdd" supply of
INT3477, so enabling dovdd via regulator_bulk_enable() also activates the
S_I2C_CTL passthrough (reg 0x43) that gates I2C access to the sensor.
No additional supply name is required in the driver.
