Pass tps68470_clk_platform_data to the tps68470-clk MFD-cell,
so that sensors which use the TPS68470 can find their clock.
Signed-off-by: Hans de Goede <hdegoede@xxxxxxxxxx>

Changes in v2:
- Put the GPIO cell last because acpi_gpiochip_add() calls
acpi_dev_clear_dependencies() and the clk + regulators must
be ready when this happens.
