media: atmel: atmel-isc-base: report frame sizes as full supported range
[ Upstream commit 72802a86e11c34e819fbfb38f58c5aef668f833d ]
The ISC supports a full broad range of frame sizes.
Until now, the subdevice was queried for possible frame sizes and these
were reported to the user space.
However, the ISC should not care about which frame sizes the subdev
supports, as long as this frame size is supported.
Thus, report a continuous range from smallest frame size up to the max
resolution.
