[PATCH 3/7] media: coda: disable encoder ioctls for decoder devices

[Philipp Zabel <p.zabel@xxxxxxxxxxxxxx>]

Use v4l2_disable_ioctl() to disable the encoder ioctls
VIDIOC_ENUM_FRAMESIZES, VIDIOC_ENUM_FRAMEINTERVALS, VIDIOC_G_PARM, and
VIDIOC_S_PARM, to fix this v4l2-compliance test failure:

		fail: v4l2-test-formats.cpp(1363): node->is_m2m && !is_stateful_enc
	test VIDIOC_G/S_PARM: FAIL
