platform/x86: int3472: Support multiple gpio lookups in board data Currently, we only support passing a single gpiod_lookup_table as part of the board data for the tps68470 driver. This carries the implicit assumption that each TPS68470 device will only support a single sensor, which does not hold true. Extend the code to support the possibility of multiple sensors each having a gpiod_lookup_table, and opportunistically add the lookup table for the Surface Go line's IR camera.

platform/x86: int3472: Pass tps68470_regulator_platform_data to the tps68470-regulator MFD-cell Pass tps68470_regulator_platform_data to the tps68470-regulator MFD-cell, specifying the voltages of the various regulators and tying the regulators to the sensor supplies so that sensors which use the TPS68470 can find their regulators. Since the voltages and supply connections are board-specific, this introduces a DMI matches int3472_tps68470_board_data struct which contains the necessary per-board info. This per-board info also includes GPIO lookup information for the sensor IO lines which may be connected to the tps68470 GPIOs.
