media: imx: Validate frame intervals before setting

Browse source 
In the .s_frame_interval() subdev op, don't accept or set a
frame interval with a zero numerator or denominator. This fixes
a v4l2-compliance failure:

fail: v4l2-test-formats.cpp(1146):
cap->timeperframe.numerator == 0 || cap->timeperframe.denominator == 0
test VIDIOC_G/S_PARM: FAIL
