ASoC: fsl_sai: fix getting version from VERID
[ Upstream commit 29aab38823b61e482995c24644bd2d8acfe56185 ]
The version information is at the bit31 ~ bit16 in the VERID
register, so need to right shift 16bit to get it, otherwise
the result of comparison "sai->verid.version >= 0x0301" is
wrong.
Fixes: 99c1e74f25d4 ("ASoC: fsl_sai: store full version instead of major/minor")
