media: hi556: Add support for reset GPIO
On some ACPI platforms, such as Chromebooks the ACPI methods to
change the power-state (_PS0 and _PS3) fully take care of powering
on/off the sensor.
On other ACPI platforms, such as e.g. various HP models with IPU6 +

Add support for having the driver control an optional reset GPIO.

media: i2c: et8ek8: Don't strip remove function when driver is builtin
Using __exit for the remove function results in the remove callback
being discarded with CONFIG_VIDEO_ET8EK8=y. When such a device gets
unbound (e.g. using sysfs or hotplug), the driver is just removed
without the cleanup being performed. This results in resource leaks. Fix
it by compiling in the remove callback unconditionally.

media: ipu-cio2: Remove unnecessary runtime PM power state setting
ipu-cio2 uses generic power management, and pci_pm_runtime_suspend() and
pci_pm_runtime_resume() already take care of setting the PCI device power
state, so the driver doesn't need to do it explicitly.
Remove explicit setting to D3hot or D0 during runtime suspend and resume.
Remove #defines that are no longer used.
