ASoC: ops: fix pointer types to be big-endian

If manipulating big-endian data, make the pointers be big-endian
instead of host-endian. This should stop the following sparse
warnigns about endian-conversion:

sound/soc/soc-ops.c:547:33: warning: invalid assignment: &=
sound/soc/soc-ops.c:547:33:    left side has type unsigned short
sound/soc/soc-ops.c:547:33:    right side has type restricted __be16
sound/soc/soc-ops.c:551:33: warning: invalid assignment: &=
sound/soc/soc-ops.c:551:33:    left side has type unsigned int
sound/soc/soc-ops.c:551:33:    right side has type restricted __be32
