The Lenovo ThinkPad X1 Fold 16 Gen 1 has an OV5675 sensor (ACPI HID OVTI5675) behind an INT3472 discrete PMIC controller. The INT3472 _DSM returns GPIO type 0x10 for one of the pins, which controls the DOVDD (digital I/O power) regulator enable. Type 0x10 is not currently handled by the driver, causing the GPIO to be ignored with a warning. Add INT3472_GPIO_TYPE_DOVDD (0x10) and handle it as a regulator with con_id "dovdd" to match the supply name used by sensor drivers (e.g. ov5675). Also increase GPIO_SUPPLY_NAME_LENGTH from 5 to 6 to accommodate the "dovdd" name (5 chars + null terminator).
