media: coda: limit frame interval enumeration to supported encoder frame sizes
[ Upstream commit 67e33dd957880879e785cfea83a3aa24bd5c5577 ]
Let VIDIOC_ENUM_FRAMEINTERVALS return -EINVAL if userspace queries
frame intervals for frame sizes unsupported by the encoder. Fixes the
following v4l2-compliance failure:
fail: v4l2-test-formats.cpp(123): found frame intervals for invalid size 47x16
fail: v4l2-test-formats.cpp(282): node->codec_mask & STATEFUL_ENCODER
test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: FAIL
[hverkuil: drop incorrect 'For decoder devices, return -ENOTTY.' in the commit log]
