media: atomisp: Put sensor ACPI devices in D3 before disable ACPI power-resources
The device core will call ACPI to turn the device (i2c_client) for a sensor
on / put it in D0 before calling its probe() method.
This takes a reference on all of the ACPI power-resources belonging to
the device. Since the atomisp_gmin_platform code disables ACPI
power-resource management and does its own pm, this reference never gets
released.
This is a problem for ACPI power-resources which are shared with other
devices since those now never get turned off again (nor back on again).
Explicitly put the device in D3 before disabling the ACPI power-resource
management.
Note that atomisp_register_i2c_module() runs near the end of the sensor
driver's probe() function, after the driver is done with probing the hw.
So the power-resouces (the same resources as directly controlled by
the atomisp platform code) getting turned off (a second time, as they are
already off) is not a problem.
