media: ti-vpe: vpe: fix a v4l2-compliance failure about invalid sizeimage

Browse source

v4l2-compliance fails with this message:

   fail: v4l2-test-formats.cpp(463): !pfmt.sizeimage
   fail: v4l2-test-formats.cpp(736): \
	Video Capture Multiplanar is valid, \
	but TRY_FMT failed to return a format
   test VIDIOC_TRY_FMT: FAIL

This failure is causd by the driver failing to handle out range
'bytesperline' values from user space applications.

VPDMA hardware is limited to 64k line stride (16 bytes aligned, so 65520
bytes). So make sure the provided or calculated 'bytesperline' is
smaller than the maximum value.
