csky: Fixup msa highest 3 bits mask
[ Upstream commit 165f2d2858013253042809df082b8df7e34e86d7 ]
Just as comment mentioned, the msa format:
cr<30/31, 15> MSA register format:
31 - 29 | 28 - 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0
BA Reserved SH WA B SO SEC C D V
So we should shift 29 bits not 28 bits for mask
