media: atmel: atmel-sama5d2-isc: fix wrong mask in YUYV format check
[ Upstream commit 91f49b80983f7bffdea9498209b2b896231ac776 ]
While this does not happen in production, this check should be done
versus the mask, as checking with the YCYC value may not include
some bits that may be set.
It is correct and safe to check the whole mask.
