imx8: isi: Disable scaling when not needed
The issue is that once the scaling was enabled, then the stream was
disabled and enabled again with a resolution that does not need scaling,
the actual scaling was never disabled in the ISI block. This made ISI
stream the scaled down with a large black padding.
