ASoC: nau8822: Fix incorrect type in assignment and cast to restricted __be16 

[ Upstream commit c1501f2597dd08601acd42256a4b0a0fc36bf302 ]

This issue is reproduced when W=1 build in compiler gcc-12.
The following are sparse warnings:

sound/soc/codecs/nau8822.c:199:25: sparse: sparse: incorrect type in assignment
sound/soc/codecs/nau8822.c:199:25: sparse: expected unsigned short
sound/soc/codecs/nau8822.c:199:25: sparse: got restricted __be16
sound/soc/codecs/nau8822.c:235:25: sparse: sparse: cast to restricted __be16
sound/soc/codecs/nau8822.c:235:25: sparse: sparse: cast to restricted __be16
sound/soc/codecs/nau8822.c:235:25: sparse: sparse: cast to restricted __be16
sound/soc/codecs/nau8822.c:235:25: sparse: sparse: cast to restricted __be16
