platform/x86: int3472: Stop using devm_gpiod_get()
The intent is to re-use the INT3472 code for parsing Intel camera sensor GPIOs and mapping them to the sensor for the atomisp driver, which currently has duplicate code. On atomisp devices there is no special INT3472 ACPI device, instead the Intel _DSM to get the GPIO type is part of the ACPI device for the sensor itself. To deal with this the mapping is done from ipu_bridge_init() instead of from a platform-device probe() function, there is no device to tie the lifetime of the gpiod_get() calls done by the INT3472 code to. Switch from devm_gpiod_get() to plain gpiod_get() + explicit gpiod_put() calls, to prepare for the code being re-used in the atomisp driver.
