media: ti: vpe: Store v4l2_fh pointer in file->private_data

Browse Source 
Most V4L2 drivers store the v4l2_fh pointer in file->private_data. The
ti-vpe driver instead stores the pointer to the driver-specific
structure that embeds the v4l2_fh. Switch to storing the v4l2_fh pointer
itself to standardize behaviour across drivers. This also prepares for
future refactoring that depends on v4l2_fh being stored in private_data.
