libcamera: v4l2_subdevice: Change V4L2Subdevice::Whence

The V4L2Subdevice::Whence enumerations defines two values that should
correspond to the V4L2_SUBDEV_FORMAT_ACTIVE and V4L2_SUBDEV_FORMAT_TRY
definitions.

The V4L2 symbols are defined as:

	V4L2_SUBDEV_FORMAT_TRY = 0,
	V4L2_SUBDEV_FORMAT_ACTIVE = 1,

While the libcamera defined enumeration is:

	enum Whence {
		ActiveFormat,
		TryFormat,
	}

As V4L2Subdevice::Whence values are used to populate data types
defined in v4l2-subdev.h used as arguments to VIDIOC_SUBDEV_*
ioctls, the V4L2Subdevice class is required to adjust their value as:

       subdevFmt.which = whence == ActiveFormat ? V4L2_SUBDEV_FORMAT_ACTIVE
                       : V4L2_SUBDEV_FORMAT_TRY;

Drop the adjustment by defining :

	Whence::TryFormat = V4L2_SUBDEV_FORMAT_TRY;
	Whence::ActiveFormat = V4L2_SUBDEV_FORMAT_ACTIVE;
